We consider the nonlinear singular differential equation where µ and σ are two positive Radon measures on 0 ω not charging points. For a regular function f and under some hypotheses on A, we prove the existence of an infinite number of nonnegative solutions. Our approach is based on the use of the
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
