报告简介：In this talk we investigate the propagation dynamics of lattice differential equations in a spatial-periodic shifting habitat. We firstshow the existence and nonexistence of periodic forced KPP waves by the minimum wave speed in the limiting environment. When the periodic forced KPP wave exists, we further establish its uniqueness and global exponential stability. Moreover, we consider periodic forced pulse waves and show a threshold result on its existence and nonexistence. Finally, we investigate the spreading properties of the solutions and indicate that the long-time behaviors of solutions depend on the speed of the shifting habitat and the minimum wave speed in the limiting environment.
