Abstract Our goal is to present approximation theorems for sequences of positive linear operators defined on \(C(X)\), where \(X\) is…

AbstractA Krasnoselskii type compression-expansion fixed point theorem is adapted for the treatment of systems of semi-Unear equations. The compression-expansion conditions…

AbstractStarting from a classification of acute myeloid leukemias which takes into account the vital characteristics of the leukemic clones, we…

AbstractIn this paper, existence results for a fourth-order nonlinear system are obtained. Both classical and vector versions of the Krasnosel’skiĭ’s…

Abstract We study the existence of nontrivial solutions to the boundary value problem \(-u^{\prime \prime}+cu\prime+\lambda u\) \( =f(x,u),\ \ -\infty<x<+\infty\)…

AbstractData dependence of fixed points for several classes of non-self generalized contractions is studied. A fibre non-self contraction theorem is…

AbstractExistence, localization and multiplicity results of positive solutions to a system of singular second-order differential equations are established by means…

AbstractIn this paper we explain the advantage of vector-valued norms and the role of matrices that are convergent to zero…

Abstract In this work, existence and localization results for \(C_1\)-solutions to elliptic Dirichlet boundary value problems are established. The approach…
