On the strongly competitive case in a two-species chemotaxis system with competitive kinetics

穆春来  重庆大学

摘要：In this talk, we consider a mathematical system of the two-species chemotaxis system with Lotka-Volterra competitive kinetic functional response term in a bounded domain with smooth boundary. The global boundedness for the solution of this system is greatly influenced by the Lotka-Volterra dynamics functional term, furthermore, the large time behavior is determined by the Lotka-Volterra dynamics term. Based on the results of previous studies, we mainly study the global boundedness for the solution of this system in the case of non-convex domain with high dimensions by constructing appropriate energy estimates, and the stability for the bounded solution of the system in strong competition case by constructing a special form of Lyapunov functional. Our results generalize some well-known results in the literature. This is a joint work with Xu Pan, Weirun Tao, Liangchen Wang.
