AbstractThe paper presents a vectorial approach for coupled general nonlinear Schrödinger systems with nonlocal Cauchy conditions. Based on fixed-point principles,…

AbstractIn this paper we develop a new theory for the existence, localization and multiplicity of positive solutions for a class…

AbstractThe purpose of the present paper is to study the existence of solutions to initial value problems for nonlinear first…

AbstractWe investigate the effect of nonlocal conditions expressed by linear continuous mappings over the hypotheses which guarantee the existence of…

AbstractIn this article, an abstract theory regarding variational properties of the fixed points of contractions and Perov contractions is applied…

AbstractIn this paper several fixed point theorems of Sadovskii type are obtained for operators on spaces endowed with two norms…

AbstractThe present paper is devoted to the existence of solutions for implicit first order differential systems with nonlocal conditions expressed…

AbstractIn this note we survey some continuation fixed point theorems for Caristi-type non-self-mappings on complete metric spaces. Two new results,…

AbstractA new variational method based on Ekeland’s principle is introduced for the existence, localization and multiplicity of periodic solutions of…
