Abstract
This paper deals with the propagation dynamics for lattice differential equations in a time-periodic shifting habitat. We prove the existence, uniqueness and global exponential stability of the periodic forced waves. We also establish the spreading properties of the solutions. Our results indicate that the long-time behaviors of solutions depend on the speed of the shifting habitat and a number that is determined by the average of the maximum linearized growth rate and the diffusion coefficient.
