Abstract
By using the continuation theorem of coincidence degree theory, sufficient and realistic conditions are obtained for the existence of positive periodi c solutions for both periodic Lotka-Volterra equations and systems with dis tributed or state-dependent delays. Our results substantially extend and im prove existing results. (C) 2001 Academic Press.
