Special Session 14: Reaction diffusion equations and applications
Contents
Reaction-diffusion systems on domains evolving in time can be studied by transforming the original system into a reaction-diffusion system on a fixed domain with time-dependent diffusion coefficients and non-autonomous reaction terms. If the original system satisfies no flux boundary conditions, a spatially homogeneous solution can be stable in the absence of diffusion (as a solution of the resulting system of ordinary differential equations), but unstable in the presence of diffusion. I will present conditions for this type of diffusion-driven instability based on results of joint work with A. Madzvamuse and Wenxian Shen and discuss work in progress.
