Theory and computation for multiple positive solutions of non-local problems at resonance
AbstractResonance non-positone and non-isotone problems for first order differential systems subjected to non-local boundary conditions are reduced to the non-resonance…
Multiple positive standing wave solutions for Schrödinger equations with oscillating state-dependent potentials
AbstractMotivated by relevant physical applications, we study Schrödinger equations with state-dependent potentials. Existence, localization and multiplicity results are established for…
A three critical point result in a bounded domain of a Banach space and applications
AbstractUsing the bounded mountain pass lemma and the Ekeland variational principle, we prove a bounded version of the Pucci-Serrin three…
Localization of positive critical points in Banach spaces and applications
AbstractTwo critical point theorems of M. Schechter in a ball of a Hilbert space are extended to uniformly convex Banach…
Two abstract approaches in vectorial fixed point theory
AbstractIn this paper a fixed point theory is established for operators defined on Cartesian product spaces. Two abstract approaches are…
Heterogeneous vectorial fixed point theorems
AbstractIn this paper, we obtain fixed point theorems for operators defined on Cartesian product spaces under heterogeneous conditions upon the…
Multiple positive solutions for a second-order boundary value problem on the half-line
AbstractIn this paper we are concerned with the existence and localization of multiple positive solutions of a boundary value problem…
Variational properties of the solutions of singular second-order differential equations and systems
AbstractThis paper is devoted to the existence and variational characterization of the weak solutions of the Dirichlet boundary value problem…
