By using the continuation theorem of coincidence degree theory, sufficient and realistic conditions are obtained for the existence of positive periodic solutions for both periodic LotkaαVolterra equations and systems with distributed or statedependent delays. Our results substantially extend and imp

This extends the study of deriving periodic solutions from bo
In this paper we give necessary and sufficient conditions for the existence of periodic solutions for convex functional differential equations of neutral type with finite and infinite delay.
The purpose of this paper is to show how the decomposition theory of linear autonomous and pseudo almost periodic systems can be used to obtain results for ''perturbed'' linear systems with pseudo almost periodic coefficients. This theory together with a natural adaptation of the methods for ordinar
