TU Dresden | Sommersemester 2024 Analytical Approaches to Evolution Equations arising in Biological Systems

In recent decades, the field of Mathematical Biology has gained a lot of popularity for several reasons. Not only do new biological insights push the frontiers of our knowledge, but the need to understand complex biological processes requires refined descriptions thereof --- a chance for mathematics to make a contribution.

We shall revisit some models introduced in MOSIM-1 & MOSIM-2. The migratory part of these models is obtained using a coarse-graining procedure of a system of coupled stochastic differential equations (SDEs), which leads to Fokker-Planck-type equations (MOSIM-2). Coupled with reaction phenomena (MOSIM-1), the resulting models belong to the family of reaction-drift-diffusion equations.

The purpose of this lecture series is to introduce analytical tools to address the well-posedness of these models and to study their behaviour. Particularly, we introduce classical linear parabolic theory, consider vanishing viscosity limits for hyperbolic equations, and, as 'grand finale' we consider the localisation limit of nonlocal interaction equations and the resulting nonlinear degenerate parabolic equations -- a timely hot topic in applied analysis.
