报告摘要：In this talk, I will discuss the existence and qualitative properties of traveling waves for spatially periodic reaction-diffusion equations with bistable nonlinearities. The spreading theory of such equations in spatially homogeneous media is well established by Fife-McLeod (1977). However, the presence of spatial periodicity makes the problem of the existence of traveling waves rather subtle. I will focus especially onthe influence of the spatial period, and discuss several existence results when the spatial period is small or large. I will also provide an example for the non-existence of traveling wave. This talk is based on a joint work with François Hamel and Xiao-Qiang Zhao.
