Kantorovich-type operators preserving affine functions
Abstract Starting from positive linear operators which have the capability to reproduce affine functions, we design integral operators of Kantorovichtype…
Statistical convergence applied to Korovkin-type approximation theory
Abstract We present two general sequences of positive linear operators. The first is introduced by using a class of dependent…
On two classes of approximation processes of integral type
Abstract The paper aims to study two classes of linear positive operators representing modifications of Picard and Gauss operators. The…
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…
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…
