报告题目: Global dynamics for some food chain models with taxis mechanism
报告摘要: Compared with the existing well-known results on the ODE type food chain systems, few results are known for the food chain model with taxis mechanism. In this talk, we first establish the existence of global classical solution for some food chain models with various type of taxis (e.g. prey-taxis and alarm-taxis ) by using the appropriately respect the particular structure and energy estimates. Moreover, by constructing Lyapunov functionals, we also establish the global stability of the spatially homogeneous steady state under certain conditions. With numerical simulations, we further demonstrate that spatio-temporal patterns are possible for the parameters outside the stability regime.
