Localization of Nash-type equilibria for systems with partial variational structure
Abstract In this paper, we aim to generalize an existing result by obtaining localized solutions within bounded convex sets, while…
Optimal finite element approximation of unique continuation
Abstract We consider finite element approximations of ill-posed elliptic problems with conditional stability. The notion of {\emph{optimal error estimates}} is…
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…
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…

Emil Cătinaș (ICTP) and Radu Precup (ICTP and UBB) are organizing the workshop Numerical Analysis, Numerical Modelling, Approximation Theory for…
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…
