Abstract: Large scale geometry is almost the dual of topology, and a large scale structure is almost dual to a topology (large scale structures are dual to uniform structures, and every uniform structure induces a topology). Topology is concerned with properties holding for smaller and smaller scales, while large scale geometry is concerned with properties … Continue reading “Ryan Jensen (Stephen F.

Abstract The mathematical treatment of realistic physics and engineering problems presents a number of difficulties, requiring, in many cases, the numerical solution of linear and nonlinear differential equations of high complexity. It is generally desirable to use numerical methods whose errors decrease rapidly with the refinement of the discretizations – so as to be able to achieve, … Continue reading “Oscar P. Burno (Caltech)”
