Abstract:In this paper, by the method of upper and lower solutions, we establish the existence of the non-trivial nonnegative periodic solutions for a class of degenerate diffusion system arising from dynamics of biological groups.
Keywords:periodic solution  nonlinear diffusion system  upper and lower solution
