Abstract

We consider a discrete almost periodic ratio-dependent Lesliesystem with time delays and feedback controls. Sufficient conditions are obtainedfor the permanence and global attractivity of the system. Furthermore, by using analmost periodic functional Hull theory, we show that the almost periodic systemhas a unique globally attractive positive almost periodic solution.
