摘要 该文运用周期抛物型算子理论,Schauder估计和分歧理论讨论了一类周期反应扩散方程,即带扩散项捕食-食饵系统的周期解的存在性,得出了系统正周期解存在的充要条件. By means of the property of periodic parabolic operators, Schauder estimates and global bifurcation theory, the coexistence state of time-periodic solutions for reaction-diffusion equations, a kind of two-species periodic predator-prey systems, are investigated. The necessary and sufficient conditions for the existence of positive periodic solutions are obtained.
