2 November 1999, Department of Mathematics, Hiroshima UniversityThe purpose of this study is to gain a better understanding of some reaction-diffusion models for bacterial colonies; such models often have the form of a noncooperative reaction-diffusion system with nonlinear diffusion and the main unknown functions are the density of a bacteria and the concentration of some nutrient.
In this talk we consider a simpler model involving
a Fisher equation with degenerate diffusion, namely
