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) + ƒ(t, xt). We prove two general theorems and establish new periodicity conditions for several population growth models.
