一类带有交叉扩散的捕食-食饵模型的全局分歧
Global bifurcation for a kind of prey-predator model with cross-diffusion
摘要
Abstract
The existence of positive solutions for Dirichlet problem with a predator-prey model with cross-diffu-sion is studied .A priori estimate of positive solution was got by using maximum principle and the existence of positive solutions was obtained with the help of Crandall-Rabinowitz bifurcation theory ,then the local bifurca-tion solution was developed to the global one ,thus the sufficient conditions of positive solutions were obtained . It has shown that predator and prey can coexist under certain conditions .关键词
