Also, by means of Schauder's fixed point theorem, we furnish, in some cases, necessary and sufficient conditions for the existence of such positive solutions. Hence, we generalize and improve the existing results for systems of Volterra nonlinear integro differential and integro difference equations. © Dynamic Publishers, Inc.eninfo:eu-repo/semantics/closedAccessArticle2-s2.0-84881251781
