## Contents

## Catalog Information

### Title

Real Analysis.

### Credit Hours

3

### Prerequisite

Math 341; 314 or 342; or equivalents.

### Description

Rigorous treatment of differentiation and integration theory; Lebesque measure; Banach spaces.

## Desired Learning Outcomes

Math 541 is a one-semester course specifically on Lebesgue integration in Euclidean space and Fourier analysis.

### Prerequisites

Currently, Math 541 requires a semester of single-variable real analysis and a semester of multi-variable Calculus. Replacing these prerequisites by Math 342 would imply that the new version of Math 541 could presuppose that students had been exposed to the geometry of **R**^{n} and to metric spaces, which would make it easier to cover the core topics listed below.

### Minimal learning outcomes

Outlined below are topics that all successful Math 541 students should understand well. As evidence of that understanding, students should be able to demonstrate mastery of all relevant vocabulary, familiarity with common examples and counterexamples, knowledge of the content of the major theorems, understanding of the ideas in their proofs, and ability to make direct application of those results to related problems.
