报告摘要:In this talk, we investigate the propagation dynamics of a reaction-diffusion competition model with seasonal succession in the whole space. Under the weak competition condition, the corresponding kinetic system admits a globally stable positive periodic solution (\hat u(t), \hat v(t)). By the method of upper and lower solutions and the Schauder fixed point theorem, we first obtain the existence and nonexistence of traveling wave solutions connecting $(0,0)$ to (\hat u(t), \hat v(t)). Then we use the comparison arguments to establish the spreading properties for a large class of solutions.
