Abstract
In this paper, we consider an almost periodic discrete multispecies Lotka-Volterra competition predator-prey system. By the almost periodicity, sufficient conditions which guarantee the existence of a unique globally attractive almost periodic solution are obtained. An suitable example together with numerical simulation indicates the feasibility of the main results.
Keywords: Almost periodic solution, predator-prey system, discrete, permanence, global attractivity.
