Linear operators generated by a probability density function
Abstract In this paper we deal with linear positive operators of both discrete and integral type. For the former we…
Mastroianni operators revisited
Abstract The present paper focuses on a class of linear positive operators introduced by G. Mastroianni. An integral extension in…
Nonnegative solutions of nonlinear integral equations in ordered Banach spaces
AbstractThe main purpose of this paper is to make Krasnoselskii’s compression-expansion fixed point theorem applicable to nonlinear integral equations in…
A note on the solvability of the nonlinear wave equation
AbstractNew existence and localization results for the nonlinear wave equation are established by means of the Schauder fixed point theorem.…
Continuation theory for general contractions in gauge spaces
AbstractA continuation principle of Leray-Schauder type is presented for contractions with respect to a gauge structure depending on the homotopy…
Existence and localization results for the nonlinear wave equation
Abstract Existence and localization results for the nonlinear wave equation are established by Krasnoselskii’s compression-expansion fixed point theorem in cones.…
Anti-periodic solutions for second order differential inclusions
Abstract In this paper, we extend the existence results presented in [9] for \(L^p\) spaces to operator inclusions of Hammerstein…
