New Subclasses of Univalent Mappings in Several Complex Variables: Extension Operators and Applications4 months agoAbstract 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 transplantation5 months agoAbstract A lower and upper solution method is introduced for control problems related to abstract operator equations. The method is…
Energy-based localization of positive solutions for stationary Kirchhoff-type equations and systems5 months agoAbstract In this paper, we are concerned with positive solutions for the Dirichlet boundary value problem for equations and systems…
Linking Methods for Componentwise Variational Systems5 months agoAbstract The paper deals with the equilibrium solutions of two-equation systems in which each component equation has a variational structure.…
Existence Results for Some Functional Integrodifferential Equations with State-Dependent Delay6 months agoAbstract 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 problems6 months agoAbstract The paper deals with fractional optimization problems where the objective function (ratio of two functions) is defined on a…
The strict superlinear order can be faster than the infinite order8 months agoAbstract The strict superlinear order (superlinear convergence) was usually regarded as having an intermediate speed between between linear and with…
Nash equilibria for componentwise variational systems8 months agoAbstract In this paper, we generalize an existing result regarding the existence of a Nash equilibrium for a system of…
On Ulam stability of a partial differential operator in Banach spaces8 months agoAbstract In this paper, we prove that, if \(\inf \limits_{x\in A}\left \vert f\left(x\right) \right \vert =m>0\), then the partial differential…
