带交叉扩散项的B-D捕食-食饵模型的全局分歧
The global bifurcation for a prey-predator model with cross-diffusion and B-D functional response
摘要
Abstract
This paper concerns the existence of positive solutions for a predator-prey model with cross-diffusion and B-D functional response under homogeneous Dirichlet boundary conditions. By the maximum principle,a priori estimate of positive solutions are obtained.By considering the related eigenvalue problems,two unbounded neutral curves are given.Then by Crandall-Rabinowitz bifurcation theory,the existence of positive solutions to a local bifurcation is proved.Finally,the local bifurcation is developed to the global one.关键词
