Global analysis of almost periodic solution of a discrete multispecies mutualism system

This paper discusses a discrete multispecies lotka-volterra mutualism system. we first obtain the permanence of the system. assuming 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. in particular,for the discrete two-species lotka-volterra mutualism system,the sufficient conditions for the existence of a unique uniformly asymptotically stable almost periodic solution are obtained. an example together with numerical simulation indicates the feasibility of the main result. © 2014 hui zhang et al.
