活动内容摘要:

This talk concerns with a reaction-diffusion system modelinh the population dynamics of two-predators and one prey with nonlinear prey-taxis. We first investigate the global existence and boundedness of solution for the general model. Then we study the global stabilities of nonnegative spatially homogeneous equilibria for an explicit system with type 1 functional responses and density-dependent death rates for the predators and logistic growth for the prey. Moreover, the convergence rates are established.
