## Mission Statement

The Department of Mathematics at Brigham Young University serves the university community and furthers the university’s mission through the pursuit of excellence in teaching, scholarship and service.

We offer a first-rate education to students, preparing them for career success in both academia and industry. Such an education inspires students, intellectually enabling them to employ critical analysis, logical deduction, thoughtful synthesis and insightful problem solving skills in any career path.

We extend the frontiers of mathematical knowledge in ways that involve students and colleagues, support the undergraduate major and graduate programs of the department, contribute to our understanding of the universe and the nature of truth, and bring positive recognition to the university.

## Graduate Programs

The Department of Mathematics has approximately 35 graduate students, and supports most of them via teaching assistantships. These students receive help with tuition as well as a stipend for the teaching support they provide in college algebra and calculus.

Two degrees are offered through the Department of Mathematics: mathematics—MS; and mathematics—PhD.

MS students study mathematics courses in preparation for careers in business, industry, government, or education. Some students use a master’s degree in mathematics in preparation for a doctoral degree in mathematics or a closely related discipline or a discipline where technical competence is appreciated. Master’s students graduate in an average of two years.

The department supports from 10-15 PhD students. Designed for gifted and dedicated students, the program requires about four years beyond a master’s degree. The department has research interests in the areas of applied mathematics, algebraic geometry, geometric analysis, dynamical systems, number theory, geometric and low-dimensional topology, mathematical biology, and group theory. PhD students graduate in, on average, four years.

## Mathematics Department

With an enrollment of nearly 30,000 full-time students, Brigham Young University, founded in 1875 as Brigham Young Academy, is one of the nation’s largest private universities and ranks 7th in the nation among all undergraduate institutions for the number of alumni who successfully complete a PhD in mathematics or statistics.

The faculty of the Brigham Young University Department of Mathematics includes some of the most renowned instructors, researchers, and mentors in the nation. They are recognized for their research and creative endeavors, innovations and discoveries, excellence as teachers and advisors, and for their outstanding service in department and university appointments.

Our faculty members have received university, college or national teaching and research awards. The math department regularly places in the top 20 of the Putnam Mathematical Competition, an annual competition for the brightest mathematical student minds in the country.

Each fall, the BYU mathematics department offers a career and internship talk series for students. We invite 5-8 guest speakers who talk about internships and careers opportunities for mathematics majors. Past speakers have included a lawyer, a doctor, an actuary, an operations researcher at communications firm, a senior scientist at a pharmaceutical company, a mathematician at Lawrence Livermore National Lab, the president of a computer company, and a financial planner at Goldman Sachs. These presentations have been very popular with an average attendance of about 200 people.

Mathematics is central to life in a technological society. The rigor and discipline required to excel in mathematics develop skills that are in constant demand. Therefore, graduates are equipped to obtain positions in a wide variety of business, governmental, and industrial enterprises. Mathematics majors are also sought after by professional schools of law, medicine, and management. Mathematical experience beyond basic calculus enhances the life and capabilities of every intellectually curious student.

**BYU Location**

Brigham Young University is located in Provo, Utah. Provo is 45 miles south of Salt Lake City, a major metropolitan area. Salt Lake City is home of the Mormon Tabernacle Choir, the Utah Jazz, the Utah Symphony, and a large number of other attractions.

**Religious Environment**

The Church of Jesus Christ of Latter-day Saints sponsors BYU to provide a university education in an atmosphere that nurtures spiritual growth and a strong conviction of the divinity of Jesus Christ. Church programs are closely correlated at all levels with the activities of the university, and students will find many opportunities to grow spiritually.

There are about twenty-five other religious denominations represented in the BYU student body. These students are encouraged to attend a congregation of their faith in the surrounding area.

**University Devotionals**

University devotionals are held throughout the year on Tuesdays at 11:05 a.m. They provide an inspirational and integrative part of the university experience. Devotional speakers, selected from the General Authorities and other leaders of the Church and university personnel, come to teach the gospel and affirm the spiritual dimension of the university experience for students, faculty, and staff.

**University Forums**

University forums are held on selected Tuesdays at 11:05 a.m. and are designed to enrich the general education experience. Speakers are noted authorities in the arts, sciences, humanities, media, and government, chosen for their contributions to their field and their ability to inspire and communicate. Participation in these assemblies and the associated question-and-answer sessions prompts inquiry into significant intellectual, cultural, and social issues and helps lay the foundation for lifelong learning.

**Harold B. Lee Library**

The Harold B. Lee Library collection numbers over eight million volumes, including books, periodicals, government documents, microfilm, and other non-print items. The library’s Web-based catalog contains numerous full-text databases and many electronic indexes to other sources.

The library is a depository for United State government documents and regularly receives publications of state and local governments.The Religion and Family History Library supports family history and genealogical research through an extensive collection of microfilm, microfiche, and online resources. L. Tom Perry Special Collections houses non-circulating books and manuscripts related to Mormonism, western Americana, incunabula, Victorian and Edwardian literature, historical manuscripts and photographs, motion pictures, and many other preserved items for research and use.

**Cultural Environment**

Students can immerse themselves in culture at BYU through the Performing Arts Series, Museum of Art, and Museum of Peoples and Cultures.

**Athletic Facilities**

BYU’s athletic facilities are among the best in the nation. The Richards Building has facilities for racquetball, volleyball, basketball, aerobics, dance, and swimming. The Smith Fieldhouse houses ball courts, weight rooms, an indoor track, and a west annex big enough for spring batting practice.

**The Great Outdoors**

The Wasatch Mountains overlook BYU on the east, and Utah Lake lies to the west. Within an hour’s drive are several canyons and ski resorts; six national parks are only a half day away. Outdoor gear may be rented on campus for everything from skiing to windsurfing.

# Applications and Admissions

**University Application Requirements**

Admission to graduate study is highly selective and is granted to a specific program for a specific semester or term. As a minimum, applicants who wish to be considered for admission must do the following:

## U.S. Applicants

- Submit a complete application before the application deadline. An application is not considered complete until the application fee has been paid and all official transcripts, letters of recommendation, the statement of intent, and the confidential report are in, as well as parts A and D of the admissions application.
- Agree to maintain university standards of personal conduct.
- Have received or be about to receive a baccalaureate degree from an accredited U.S. or Canadian university. The Office of Graduate Studies must receive an official transcript showing that the degree has been conferred. Without such verification, registration will not be permitted beyond the first semester. U.S. students with a degree from a foreign university equivalent to an American baccalaureate must submit official transcripts from all institutions attended and an accompanying certified translation.
- Have earned at least a 3.0 GPA in the last 60 semester hours of coursework.
- All applicants for whom English is not the native language: Submit evidence of proficiency in English.
- Have a score of at least 600 on the GRE Math Subject Test.
- Satisfy departmental requirements for consideration. See all the sections under Mathematics Department Application and Admission Requirements.

## International Applicants (all non-U.S.)

- Submit a complete application before the application deadline. An application is not considered complete until the application fee has been paid and all official transcripts, official evidence of degrees earned, letters of recommendation (Part C), the statement of intent, official TOEFL score, financial certification, and the Code of Honor commitment and confidential report (Part B) are in, as well as Parts A and D of the admissions application.

- Submit a TOEFL score of at least 580. To be competitive for financial support, a TOEFL score of at LEAST 600 or a computer equivalent score of at least 237 is preferred. This is required of all applicants for whom English is not the native language. Students with a bachelor’s degree from a U.S. or Canadian university are usually exempt from this requirement.
- Have a score of at least 600 on the GRE Math Subject Test.
- Submit a completed Financial Certification and Visa Information form with supporting documents. Applicants must provide proof of sufficient funds for the total length of their program of study.
- Satisfy departmental requirements for consideration. See all the sections under Mathematics Department Application and Admission Requirements.

**Note:**Brigham Young University will not process applications from applicants entering the United States with a B visa. An admitted student will receive an I-20 or IAP-66 form (Certificate of Eligibility) with the official letter of acceptance; the I-20 and IAP-66 are used to obtain a student visa (F-1 or J-1).

# Financial Support and Employment

Most of the graduate students in mathematics are supported by teaching assistantships. The usual load for a teaching assistant is twenty hours a week. Teaching assistants currently receive a stipend of $6,200 for MS and $18,500 for Ph.D. per calendar year. Some research or travel funding is available for those students who are making good progress toward a degree, and who have submitted a program of study and have an advisor’s endorsement.

To be considered for financial support, applications should be submitted by January 15 for fall semester and September 15 for winter semester.

## Guidelines for the Continuation of Financial Support

Continued financial support is recommended for graduate teaching assistants who are making satisfactory progress in an approved program of study and who are judged satisfactory in their teaching duties. Quality teaching performance is essential for continuation. Unsatisfactory teaching may lead to loss of support, and cases of conspicuous irresponsibility or neglect will be cause for immediate termination.

## Employment Outside the Mathematics Department

The combined obligations of teaching and studying are full-time undertakings. The Department of Mathematics does not permit teaching assistants to assume any additional form of employment.

## Teaching Loads and Tuition Waivers

The normal teaching load for a teaching assistant is twenty hours per week. Duties include teaching, grading, holding office hours, recitations, and working in the Math Lab.

In addition, full tuition for mathematics courses will generally be provided for teaching and research assistants during fall and winter semesters, provided they make adequate progress in their programs of study and regularly attend an appropriate seminar and the TA training (if applicable). Tuition may also be paid in spring and summer, depending on department budget constraints.

The department will not pay additional tuition for courses that are not on the student’s program of study. For example, a student enrolled in six hours of mathematics courses and three hours of physical education courses will have tuition paid only for the six hours of mathematics courses. However, a student who is enrolled full-time (9 hours) in mathematics courses will have full-time tuition paid by the mathematics department. Thus that student may take additional non-mathematics courses that do not interfere with performing other responsibilities without charge. Students may petition the graduate committee to take courses outside the math department, provided the courses are relevant to their program of study and have been approved by their advisors.

# Living Expenses and Tuition

## Tuition

A significant portion of the cost of operating the university is paid from the tithes of The Church of Jesus Christ of Latter-day Saints (LDS). Therefore, students and families of students who are tithe-paying members of the Church have already made a contribution to the operation of the university. Because others have not contributed in this way, they are charged a higher rate of tuition, as shown below. This practice is similar in principle to that of state universities that generally charge nonresidents at a higher rate than residents.

## Graduate Tuition 2016-2017

http://finserve.byu.edu/content/tuition-and-general-fees

### Fall and winter semesters:

Full-Time (8.5+ hours) LDS: $3,340 Non-LDS: $6,680

Part-Time (per credit hour) LDS: $393 Non-LDS: $786

### Spring and summer terms:

Full-Time (4.5+ hours) LDS: $1,670 Non-LDS: $3,340

Part-Time (per credit hour) LDS: $382 Non-LDS: $764

Teaching and research assistants receive a tuition scholarship for mathematics courses fall and winter semesters if they are making good progress toward completion of their program.

# Program Purpose and Objectives

The general objective of the Department of Mathematics at Brigham Young University, as related to the degrees offered by the Department, is to teach mathematics and mathematical thinking at the level appropriate to each student. This enables students to employ critical analysis, thoughtful synthesis, logical deduction, and insightful problem solving, not only within mathematics itself but also in a wide variety of natural and man-made situations

## MS Objectives

The Master of Science program is specifically designed to help students as they progress towards becoming independent mathematical thinkers, and participate in advancing the frontiers of mathematical knowledge. The program also prepares students for positions in business and industry that require advanced mathematics skills, critical analysis, thoughtful synthesis, and insightful and independent problem solving.

## PhD Objectives

The specific purpose of the Doctor of Philosophy program in Mathematics is to prepare students for a career in research and teaching at the university level. It also prepares them for professions that require independent mathematical research, advanced mathematical knowledge, critical analysis, thoughtful synthesis, and insightful and independent problem solving. It gives students an opportunity to become full contributors to the important and exciting process of extending the frontiers of mathematical knowledge.

The underlying philosophy of the program is that graduate-level mathematics is both enabling and ennobling. Mathematical knowledge, logical reasoning, and the ability to solve problems and discover mathematical truths are powerful and important skills that promote student success in a wide range of academic, professional, or business-related careers.

But more importantly, deep and careful mathematical thought expands both the mind and the soul. It increases understanding of many things, both physical and spiritual. Our purpose in this program is to enrich the spiritual and temporal lives of our students by sharing the beauty and power of mathematics with them.

The accomplishment of these objectives requires the students to gain a deep understanding of and appreciation for mathematics, its versatility, depth, and power. They must also understand important ideas of the main mathematical subdisciplines and the relationship of mathematics to other subjects.

Finally, students should be able to work independently, without the direct supervision and guidance of a senior mathematician. The development of this independence is certainly begun at the undergraduate and masters levels, but for most students it can only be fully achieved at the doctoral level. Although coursework plays some role in the requirements for the Ph.D. in mathematics, the most important element is the dissertation, a significant and substantial work of original mathematical research.

Specific goals of the programs

The specific goals of the MS in Mathematics are to help each individual student.

- Achieve an understanding of graduate-level mathematics, including several areas such as Analysis, Algebra, Topology, and Applied Mathematics.
- Achieve depth and application in a specialized area.
- Develop mathematical research skills.
- Develop problem-solving skills applicable to a wide variety of settings.

# Program Requirements and Offerings

The Department of Mathematics offers a master’s and a doctoral program. The Master of Science (M.S.) program prepares students for positions in business and industry, and also provides preparation for further graduate study leading to a doctoral degree at Brigham Young University or elsewhere.

The Doctor of Philosophy (Ph.D.) program prepares students for a career in research and teaching at the university level. The Ph.D. program in Mathematics was approved in 1986 when the Department received a program improvement grant to fund teaching assistantships in mathematics. The current research areas of the faculty include: algebraic geometry, applied mathematics, dynamical systems, combinatorics, geometric and low-dimensional topology, geometric and combinatorial group theory, number theory, numerical methods, mathematical biology, and partial differential equations.

With small classes and individual attention, the department supports high quality research programs in the selected areas.

### Forms

All forms needed for graduate studies may be downloaded from the following website:

http://graduatestudies.byu.edu/content/all-forms

## Mathematics M.S. Degree

**Approved Courses (Both Thesis and Non-Thesis Programs)**

Approved graduate mathematics courses include all classes numbered 500 and above, with the exception of Math 500. All courses must be passed with a grade of C+ or better. No credit is given for prerequisite courses such as Math 342 or Math 372.

Students are required to submit a program of study before the end of the third week of their second semester. The study list form may be found at http://graduatestudies.byu.edu/sites/default/files/graduatestudies.byu.edu/files/files/forms/adv_form_3.pdf

** Note: **The minimum registration requirement is six credit hours per year. Students not meeting this requirement will be dropped from the program.

### Thesis Program Requirements

- Credit hours (30): Minimum 24 coursework hours in approved graduate mathematics with a grade of C+ or better in each and six thesis hours (Math 699R). Twelve of the course hours must be from Math 540, Math 541, Math 571, and Math 572 or any 600-level course.
- Examination: Each student must pass a written master’s examination consisting of two 4-hour tests, namely an algebra exam and an analysis exam, essentially covering material from Math 313, Math 371, Math 372 or Math 473 for algebra, and Math 341, Math 342, and Math 352 for analysis. TThe exams will be administered three times per year. Both exams must be passed within the first year of matriculation in order for financial support to continue. This means that students will have three attempts as graduate students. With permission, however, undergraduates and other prospective graduate students can take and pass the exam early, prior to matriculation. Exams will typically be scheduled for the week prior to the start of classes for Fall and Winter terms, usually the last week of August and first week of January. It will also be administered in mid to late February, usually during the President’s day weekend. It is expected that exams will be graded and returned to the students within a week. Students will be encouraged to discuss the results of the exam with their advisors to decide which classes to take. If students do not pass both exams by the end of their first academic year, financial support will be discontinued at the end of that semester. For example, if a student fails his third attempt in February, his last semester in the program will be that winter semester, and he will not be financially supported in the following spring and summer terms.
- Thesis. Each student in the program is required to write a thesis (or project) on a mathematical topic at a level well beyond what they encounter in the classroom. The master’s thesis (or project) usually includes an introductory chapter that is a comprehensive survey of the literature on the student’s research topic. Upon completion of the thesis (or project) and before graduation, the student is required to give an oral presentation of his work. The department tracks student publications in professional journals and student presentations in professional meetings
- Oral defense of thesis. Defenses must be scheduled AT LEAST two weeks before the date of the defense. Students will not be permitted to defend their theses until their faculty advisors have approved their work. To schedule the final oral exam, bring the completed ADV Form 8c to the graduate secretary.

### Non-Thesis Program Requirements

- Credit hours (32): Minimum 30 coursework hours in approved graduate mathematics with a grade of C+ or better in each and two hours for the project (698R). Eighteen course hours must be taken from Math 540, 541, 571, and Math 572 or courses numbered 600 or above. No credit is given for prerequisite courses such as Math 342 or Math 372.
- Examination: Each student must pass a written master’s examination consisting of two 4-hour tests, namely an algebra exam and an analysis exam, essentially covering material from Math 313, Math 371, Math 372 or Math 473 for algebra, and Math 341, Math 342; and Math 352 for analysis. The exams will be administered three times per year. Both exams must be passed within the first year of matriculation in order for financial support to continue. This means that students will have three attempts as graduate students. With permission, however, undergraduates and other prospective graduate students can take and pass the exam early, prior to matriculation. Exams will typically be scheduled for the week prior to the start of classes for Fall and Winter terms, usually the last week of August and first week of January. It will also be administered in mid to late February, usually during the President’s day weekend. It is expected that exams will be graded and returned to the students within a week. Students will be encouraged to discuss the results of the exam with their advisors to decide which classes to take. If students do not pass both exams by the end of their first academic year, financial support will be discontinued at the end of that semester. For example, if a student fails his third attempt in February, his last semester in the program will be that winter semester, and he will not be financially supported in the following spring and summer terms.
- Project, Paper and Presentation: Complete a project (Math 698R) focused on an area of advanced mathematics, write a paper about the project, and present a 45-minute talk based on the paper.

## M.S. Degree Recommended Schedule of Study

Below is a recommended schedule of courses for students in the master’s program. Students should consult with their advisor to determine whether some deviation from this plan is better suited to their individual needs. The standard load for a student with a teaching or research assistantship is 9 credit hours of graduate-level mathematics courses per semester. Students who enroll in fewer mathematics courses may have trouble completing their program requirements in a timely manner. Students not enrolled in at least six hours of mathematics courses per semester are generally not making satisfactory progress toward completion of their degree and may have their funding reduced or their degree candidacy terminated.

**Semester 1 (Fall)**

- Take Math 541, Math 553, and Math 571 or Math 510, or other courses as directed by your (perhaps temporary) advisor.
- Attend the weekly graduate seminar and department colloquia.
- Choose an advisory committee and prepare a study list.
- Take the master’s algebra and analysis exams in August.

**Semester 2 (Winter)**

- Take Math 540, Math 554, and Math 572, or other courses as directed by your advisor.
- Submit your study list before the
**end of the third week**of the semester. - Attend the weekly graduate seminar.
- Pass the master’s exams (in January and February if necessary).

**Spring/Summer**

- Begin the thesis or project.
- Take reading courses relevant to the thesis or project, as directed by your advisory committee.

**Semester 3 (Fall)**

- Take at least three hours of 600-level courses.
- Take six more hours of courses according to your study list (some may be thesis or project hours).
- Attend a weekly research seminar as directed by your advisor, and attend department colloquia.
- Continue work on your thesis or project.

**Semester 4 (Winter)**

- Take at least three hours of 600-level courses.
- Take six more hours of courses according to your study list (some may be thesis or project hours).
- Attend a weekly research seminar as directed by your advisor.
- Finish and defend the thesis or project.

## Master’s Examinations

The content of the examinations are based on Algebra (Math 313, 371 and 372, or 473) and Analysis (Math 341, 342, and 352).

Previous exams may be used as study guides. Students are allowed to take the examination three times during their first year of graduate study in August, January and February. A student is allowed to take the master’s exam as an undergraduate and not have this attempt count as one of the three allotted for the first year of graduate study. Students are encouraged to participate in the departmental Boot Camp held each August to prepare for these exams.

## Guidelines for M.S. Degree Projects and Theses

**Content**

A mathematics MS project should entail learning mathematics not normally taught in graduate or undergraduate classes. It may be of an expository nature or may involve the investigation of mathematical structures in some depth. It does not need to include original research, but it should include some proofs.

A mathematics MS thesis should be a substantial mathematical work. This does not only refer to length, but rather to content. Students should pursue original work sufficient for publication in a college mathematics journal. The thesis should be the work of the student and should not be written primarily by the advisor. Other than original work the thesis might be an account of work at the frontier of research in a particular area, perhaps including new examples worked out in detail.

Computational/algorithmic projects or theses are also possible; however, the mathematical content needs to be the core of the writing.

Students should be stretched and will be called to account for the logical content of their written work. They should contribute in some way to mathematics and not just reiterate what they have already learned.

Students should be aware of the limitations of their methodology (e.g. statistical significance) yet also be aware of the possibilities for amplification of their results. They should have a broad view of the subject matter and how what they have done fits into the general subject.

**Presentation or Defense**

The student should give a presentation in which the essential ideas of the written work are exposed and put into context. The student should be able to answer straightforward questions on the basic parts of their work, indicating a thorough understanding. The talk should include at least one proof. You MUST schedule your defense AT LEAST two weeks before the date you want to present. Bring the completed ADV Form 8c to the graduate secretary to schedule the defense.

## Mathematics Ph.D. Degree

**Credit Hours (54):**Minimum 36 coursework hours in mathematics courses numbered 600 or above (540, 541, 571, 572 may be substituted) with a grade of B or better in each plus 18 dissertation hours (Math 799R).**Required Courses:**Complete at least three hours each in Algebra, Analysis, Applied Mathematics, and Geometry/Topology.**Examinations:**- Written Examinations: Graduate students will be required to pass a PhD prelim exam during their first year in the areas of Algebra, Analysis, ODEs or Topology. The material tested will be taken from 541 (analysis) and 553 (topology), and 571 (algebra). There will be four questions taken from each of these three areas. This exam will be offered in January, May, and August of each year. A passing grade of 66% in each area is necessary, however if the student only passes in two such areas, then he/she needs to take a 600 level class in the remaining area and achieve an A/A- grade in that class. Another scenario for passing is that a student passes in two of the three subjects in August and passes the third in January or May; 4.5 hours are allotted to each examination.
- In their first and second years the student needs to pass three qualifying exams. One of these must be in algebra or analysis; the student and his/her committee will determine the others. The material tested will be from Math 540/641 for analysis and Math 572/673 for algebra. For topology the courses would be Math 554/656. These exams will be offered in January, May, and August of each year. Four hours are allotted to each examination.
- Defense of Dissertation: A final oral defense of the dissertation is conducted by a faculty committee consisting of the student’s research advisor and four other members of the faculty (one of whom must be an outside examiner). Defenses must be scheduled
**AT LEAST**two weeks before the date of the defense. Students will not be permitted to defend their theses until their faculty advisors have approved their work. To schedule the final oral exam, bring the completed ADV Form 8c to the graduate secretary.

**Dissertation:**A student seeking a doctor of philosophy degree must register for and complete a minimum of 18 hours of dissertation credit. No more than 18 hours may count toward the 54 hours required, and all 18 hours may not be taken in one term or semester. Registration for dissertation credit and work on the dissertation must be concurrent.

### Ph.D. Degree Recommended Schedule of Study

The following schedule is recommended for teaching assistants in the Ph.D. program. Except where there are extenuating circumstances, teaching assistants who fall more than one year behind this schedule should not expect their teaching assistantships to be renewed. Students who have strong potential but lack adequate preparation may petition to have a year zero added in which they complete their preparation for the Ph.D. program. During this year, their teaching duties and pay will be similar to master’s students. Students who have passed fewer than two of the three required qualifying examinations by February of their second year will not be allowed to continue. Students who have passed only two of the three examinations by February of the second year may request special permission to continue for an additional year by submitting a written request to the student’s graduate committee. The student’s committee reviews the request and submits a written recommendation to the departmental graduate committee. In addition, students who have completed an M.S. degree at BYU are required to pass at least one examination by February of their first year of study in the Ph.D. program in order to continue beyond the first year.

Year 1

- Take three 600-level yearlong mathematics sequences.
- Attend the weekly graduate seminar (or a research seminar, as directed by your advisor).
- Select an area of specialty, an advisor, and advisory committee.
- Attend department colloquia.
- Prepare a study list in consultation with your advisor (due during the first year, and no later than the first week of second year).
- Pass at least one qualifying exam if you were a BYU MS student, or pass the preliminary exam if you were not.

Year 2

- Take nine credit hours of advanced graduate courses each semester, ideally in yearlong sequences (Dissertation hours may suffice for some of these credit hours).
- Attend a weekly research seminar, as directed by your advisor.
- Attend department colloquia.
- Pass three written qualifying examinations by the end of the year.

Year 3

- Continue taking advanced graduate courses.
- Actively participate in research seminars.
- Attend department colloquia.
- Begin work toward a dissertation.

Year 4

- Devote primary attention to finishing the dissertation.
- Continue participating in advanced courses and seminars.
- Consider publishing dissertation results in a journal and present them at a professional conference.
- Find research topics to pursue beyond a dissertation and begin to develop a long-term research plan.
- Complete the requirements for the doctoral degree.

*Note*: It is expected that students attend a seminar of their choice as well as colloquia throughout their programs

# Advisement

## Temporary Advisor

Once accepted into the graduate program, students are assigned a temporary advisor who guides their first registration and individual study until the student selects an advisory committee, which is appointed in the first semester. Students should contact their temporary advisor well before their first semester of graduate study so that they can be sure to enroll in courses best suited to their individual case.

## Advisor and Advisory Committee

The advisor plays a significant role in guiding the student through the program and helping the student become an independent mathematician. The advisor helps the student choose a project, thesis, or dissertation topic, and gives guidance and supervision throughout the task.

## Choosing an Advisor

The main component in choosing a professor to be an advisor should be to match the student’s research interests with the type and quality of research done by the professor. In order to determine the type of research currently being done by faculty members, students should attend the various seminars offered. Once a student has determined that someone has similar interests, the student should then consult with the professor and ensure that he or she is willing to act as an advisor.

## Advisory Committee

During the first semester, students should work with the selected advisor to arrange for the appointment of an advisory committee. Master’s (thesis and project) committees consist of a chair and at least two other members; doctoral committees have a chair and at least four other members. The Department may require additional members.

## Program of Study List

The goal of the graduate program in mathematics is for the student to become an independent mathematician. This is not accomplished by taking a random selection of courses but by carefully working with an advisory committee to create a program that has a solid mathematical foundation and meets the student’s interests.

A program of study list (http://graduatestudies.byu.edu/sites/default/files/graduatestudies.byu.edu/files/files/forms/adv_form_3.pdf must be submitted and approved by the student’s advisory committee.

Master’s students should complete the program of study list under the direction of their graduate committee during the student’s first semester, and in no case later than the third week of the second semester. A master’s committee must consist of a chair and at least two members.

Doctoral students should receive approval and submit their program of study during the first year, and in no case later than the third week of the beginning of the second year of study. A doctoral committee must consist of a chair and at least four members.

Financial support will be reduced and may be withdrawn if a study list is not submitted on time. The Graduate Study List gives the approved courses of study for the graduate degree. It is possible at any time to amend the study list for courses not yet taken. A program of change form may be accessed at the following website:

After the list has been filled out and the appropriate signatures have been obtained, the list should be returned to the department graduate secretary.

In addition to the official study list, by the end of October of each year, students should submit a tentative schedule of when they plan to take each remaining course on their study list. This allows the graduate committee to ensure that graduate course offerings for the coming year will meet students’ needs.

# Graduation and Evaluation of Student Progress

## Graduation Deadlines

## Graduation

The Math Department encourages students to complete their degree programs in a timely fashion. An MS degree is expected to take two years to complete while a PhD should take four years. We understand that unavoidable delays may occur, plans may change, and personal challenges may arise. However, taking too much time to graduate reflects poorly on the student, advisors, and department. Students should not extend the time it takes to graduate.

For instructions to apply for graduation, visit the following website: https://graduatestudies.byu.edu/content/applying-graduation

### Evaluation Process

I. The Math Department will monitor graduate student progress twice a year (usually fall semester and spring term).

A. The graduate committee will review the progress of each student.

B. Students will be rated as making satisfactory, marginal, or unsatisfactory progress.

- If marginal or unsatisfactory progress is noted, students will be notified in writing what they need to do, when it needs to be accomplished, and who to contact for help to demonstrate satisfactory progress.
- Students who receive an unsatisfactory evaluation will not be eligible to obtain financial support.

C. Students will be notified in writing of their progress. The letter will contain information regarding the following:

- What they need to do to make satisfactory progress,
- When each task needs to be accomplished,
- Which faculty member(s) they should contact for more information or support,
- What will happen if these tasks are not accomplished (e.g., an unsatisfactory rating for the next semester, termination from the program, etc.).

II. Definitions of ratings:

A. Satisfactory progress includes the following:

- On track in all things to successfully graduate within the proper time frame.
- No concerns with departmental responsibility.

B. Marginal progress includes the following:

- Failure to submit program of study form within the first two semesters.
- Failure to establish a graduate committee within the first two semesters.
- Registering for thesis hours but doing little or no work.
- Minimal contact with chair or advisory committee members.
- Failure to maintain a 3.0 GPA.
- Earning an unacceptable grade in a study list course (C+ grade for master’s students, and a B grade for doctoral students).
- Unsatisfactory performance of departmental responsibilities.

C. Unsatisfactory progress includes the following:

- Failing a course.
- Not progressing at a rate necessary to finish all courses in a timely manner.
- Not meeting the requirements set forth in a previous marginal evaluation.
- Poor performance in research.
- Lack of ethics.

III. If a student receives a marginal and an unsatisfactory or two unsatisfactory ratings in succession the department will:

A. Terminate the student’s program at the conclusion of the semester **OR**

B. Submit a Petition for Exception (OGS Form 2) to Graduate Studies making a convincing case that the student be given another semester to demonstrate satisfactory progress. A copy of a contract to completion listing student and faculty responsibilities and a time line must be attached. This document will include the signatures of the student and the student’s graduate committee. Note: The completion deadline in AIM will be shortened based on the contract to completion.

IV. If a student receives a marginal rating in one semester and is not making satisfactory progress in the next semester, the student will be rated as making unsatisfactory progress. A student will not be rated as making marginal progress in two sequential semesters. Failing to correct marginal progress is unsatisfactory

# Graduate Student Advisory Committee

The Graduate Student Advisory Committee exists to improve the graduate program by:

- Advising graduate students concerning classes, requirements for degrees, and other aspects of the graduate program.
- Making recommendations concerning the graduate program to the Department of Mathematics.
- Assisting the Department in making its policies and requirements fully understood by the graduate students.
- Organizing the weekly graduate seminar.

This committee consists of three graduate students, elected in the fall of each year by the mathematics graduate students. If there are not sufficient nominations, the Graduate Committee may nominate or select members of this committee.

# Courses and Seminars

## Seminars

Part of becoming an independent mathematician is becoming exposed to a broad range of mathematical research as well as studying some specific areas in greater depth. It is expected that students attend colloquia and a seminar of their choice. Students receiving tuition awards are expected to attend the graduate seminar or, with the approval of their advisor, a research seminar at least 11 weeks per semester. Students are expected to attend at least five department colloquia a semester.

The graduate seminar is a weekly seminar organized by the Graduate Student Advisory Committee. Its purpose is to acquaint students with the faculty and their research, prepare students for the department colloquia, and to permit students an opportunity to share their research with other students. As students advance in the program, it is generally expected that they will attend a regular research seminar instead of or in addition to the graduate seminars.

The research seminars usually include the following:

- Algebra
- Algebraic Geometry
- Dynamical Systems
- Mathematical Biology
- Mathematical Physics
- Number theory
- Partial Differential Equations
- Stochastic Differential Equations
- Topology

Other seminars also run from time to time. Please see the Seminar Page for more information. https://math.byu.edu/upcoming-seminars-colloquia/

**Non-core courses**

Other courses are offered less regularly. Consult the course schedule to check availability.

All students should submit their program of study by the end of November of their first year. Students must also submit an additional list to the secretary, giving a schedule of when they plan to take the courses in their programs of study. Students should consult with their advisors to select the most beneficial courses, and to decide when they should take them. The graduate committee uses these lists to determine which classes will be taught the next year, and to ensure that students’ coursework needs are met.
