| Research Abstract |
This research project deals with such themes as (1) traveling waves in nonlinear diffusion equations, (2) singular limit of nonlinear diffusion equations and interface motion, (3) blow-up in nonlinear heat equations, (4) mathematical analysis of 3D cellular electrophysiological model. The theme (4) was added after the program began. In theme (1), we studied, among other things, traveling waves colliding with obstacles, the stability of planar waves, and the problem of maximizing traveling wave speeds. In theme (3) we studied, among other things, classification of blow-up in Sobolev superlinear heat equations, and an application the theory of braid groups to the dead-core problem.
