题  目: Degenerate Reaction-Diffusion Systems and Applications

时  间: 6月21日（周四）下午16:30

摘  要: In this talk, we study the case that some species migrate from densely populated areas into sparsely populated areas to avoid crowding, and investigate a more general reaction-di usion system by considering density-dependent dispersion as a regulatory mechanism of the cyclic changes. Under certain conditions, we apply the higher terms in the Taylor series and the center manifold method to obtain the local behavior around a non-hyperbolic point of codimension one in the pase plane, and use the Lie symmetry reduction method to explore bounded traveling wave solutions. Numerical simulation and biological explanation are presented.
