AbstractMotivated by relevant physical applications, we study Schrödinger equations with state-dependent potentials. Existence, localization and multiplicity results are established for…

AbstractUsing the bounded mountain pass lemma and the Ekeland variational principle, we prove a bounded version of the Pucci-Serrin three…

AbstractTwo critical point theorems of M. Schechter in a ball of a Hilbert space are extended to uniformly convex Banach…

AbstractIn this paper a fixed point theory is established for operators defined on Cartesian product spaces. Two abstract approaches are…

AbstractIn this paper, we obtain fixed point theorems for operators defined on Cartesian product spaces under heterogeneous conditions upon the…

AbstractIn this paper we are concerned with the existence and localization of multiple positive solutions of a boundary value problem…

AbstractThis paper is devoted to the existence and variational characterization of the weak solutions of the Dirichlet boundary value problem…

AbstractThe purpose of the present paper is to study the existence of solutions to semilinear evolution systems with nonlinear constraints.…

AbstractWe study the existence, localization and multiplicity of positive solutions for a nonlinear fourth-order two-point boundary value problem. The approach…

AbstractUsing Ekeland’s variational principle we obtain a critical point theorem of Schechter type for extrema of a functional in an…
