报告摘要 Abstract: 

In this talk, we discuss the global boundedness and asymptotic stability of a Lotka-Volterra competition system in a two-dimensional bounded domain with Neumann boundary conditions, where the motility (diffusion and/or advection) of two competing species depends on the distribution of the resource that satisfies a dynamical reaction-diffusion equation. We first establish the existence of classical solution with uniform-in time bound. Then by constructing Lyapunov functionals, we establish the global stability of the spatially homogeneous exclusion steady states and coexistence steady states under certain conditions on parameters. Our result is a development of existing results where the resource is a given function of space or time instead of one determined by an evolutionary equation as considered in our present work.
