Abstract

In this paper, we employ Krasnosel'skii's fixed point theorem for cones to study the existence of positive periodic solutions to a system of infinite delay equations, x?(t) = A(t)x(t) + f(t,xt). We prove two general theorems and establish new periodicity conditions for several population growth models. © 2002 Southwest Texas State University.
