On the positive almost periodic solutions of a class of Lotka-Volterra type systems with delays

In this paper we study the existence of positive almost periodic solutions for a class of almost periodic Lotka-Volterra type systems with delays. Applying Schauder's fixed point theorem we obtain a general criterion of the existence of positive almost periodic solutions. This criterion can be used not only in the case of finite delay but also in the case of infinite delay. (C) 2000 Academic Press.
