报告摘要:

In this talk, I will report recent works on global dynamics and complex patterns in the Lotka-Volterra competition system with effects of nonlocal competitions. We obtain the global dynamics, the existence of Hopf、Turing and Turing-Hopf bifurcations, and reveal complex spatiotemporal pattern near the co-dimension two Turing-Hopf bifurcation point by using the center manifold theory and normal form reduction method, depending on the strength of nonlocal intraspecific competition.
