Almost Periodic Solution of a Discrete Multispecies Type Competition-predator System

In this paper, we consider a discrete multispecies Gilpin-Ayala type competition-predator system. Firstly, permanence of the system is studied. Assume that the coefficients in the system are almost periodic sequences, we obtain the sufficient conditions for the existence of a unique almost periodic solution which is globally attractive by the almost periodicity. Two examples together with numerical simulation indicate the feasibility of the main results.
