Professor Yoshio Yamada of Waseda Univ (Japan) will give a talk at
Tuesday 3.10pm in MC206.
Title: Population models with nonlinear diffusion.
We will discuss Lotka-volterra competition models with nonlinear
diffusion. Under some conditions, these models exhibit segregation
phenomena between two competing species due to cross-diffusion effects.
We will give some recent results on global solutions for the
nonstationary problems and the structure of positive solutions for the
