Perov’s theorem applied to systems of equations
Abstract In this paper, we consider systems of equations having a linear part and also a nonlinear part. We give…
Testing Weyl geometric gravity with the SPARC galactic rotation curves database
Abstract We present a detailed investigation of the properties of the galactic rotation curves in the Weyl geometric gravity model, in which…
Positive radial solutions for Dirichlet problems in the ball
Abstract We are concerned with existence, localization and multiplicity of positive radial solutions to Dirichlet problems with φ-Laplacians in a ball, in both…
On the iterates of uni- and multidimensional operators
Abstract The problem of the convergence of the iterates of operators or of a sequence of operators is discussed in…
Păltănea’s operators: old and new results
Abstract This note concerns the study of an approximation linear positive process introduced by R. Paltanea in 2008. Considering the…
Role of partial functionals in the study of variational systems
Abstract Applying techniques originally developed for systems lacking a variational structure, we establish conditions for the existence of solutions in…
New Subclasses of Univalent Mappings in Several Complex Variables: Extension Operators and Applications
Abstract In this paper we define new subclasses of univalent mappings in the case of several complex variables. We will…
A method of lower and upper solutions for control problems and application to a model of bone marrow transplantation
Abstract A lower and upper solution method is introduced for control problems related to abstract operator equations. The method is…
Existence Results for Some Functional Integrodifferential Equations with State-Dependent Delay
Abstract In this work, we establish sufficient conditions for the existence of solutions for some functional integrodifferential equations with state-dependent…
Componentwise Dinkelbach algorithm for nonlinear fractional optimization problems
Abstract The paper deals with fractional optimization problems where the objective function (ratio of two functions) is defined on a…
