Generalized Rough Sets Applied to BCK/BCI-Algebras
Discussiones Mathematicae - General Algebra and Applications, 2021 The concept of a (strong) set-valued BCK/BCI-morphism in BCK/BCI-algebras is considered, and several properties are investigated. Conditions for a set-valued mapping to be a set-valued BCK/BCI-morphism are given.

Rough semi-continuous set-valued maps
, 2021 Summary: In this paper, we introduce the concepts of rough semi-continuity and rough continuity of set-valued maps. Then we investigate the question whether these concepts may be characterized differently or not.

Abstract and Applied Analysis, 2013 We study the connectedness of solution set for set-valued weak vector variational inequality in unbounded closed convex subsets of finite dimensional spaces, when the mapping involved is scalar C-pseudomonotone.

On some weak conditions of commutativity in common fixed point theorems
International Journal of Mathematics and Mathematical Sciences, 1988 We generalize common fixed point theorems of Fisher and Sessa in complete metric spaces, using some conditions of weak commutativity between a set-valued mapping and a single-valued mapping. Suitable examples prove that these conditions do not imply each

Berge's Theorem for Noncompact Image Sets
, 2012 For an upper semi-continuous set-valued mapping from one topological space to another and for a lower semi-continuous function defined on the product of these spaces, Berge's theorem states lower semi-continuity of the minimum of this function taken over

Quantitative stability analysis of stochastic generalized equations [PDF]
, 2014 We consider the solution of a system of stochastic generalized equations (SGE) where the underlying functions are mathematical expectation of random set-valued mappings.

Nonlinear Generalizations of Tucker's Theorem on Inequality Systems [PDF]
, 1999 This note is to prove Tucker's theorem on linear inequalities based on the proof method of minimax theorems which uses Kakutani's fixed point theorem. One device is necessary to convert the minimax theorems to Tucker's formulation.

, 2006 We consider the perturbed harmonic oscillator $T_D\psi=-\psi''+x^2\psi+q(x)\psi$, $\psi(0)=0$, in $L^2(\R_+)$, where $q\in\bH_+=\{q', xq\in L^2(\R_+)\}$ is a real-valued potential. We prove that the mapping $q\mapsto{\rm spectral data}={\rm \{eigenvalues

Existence of basic solutions of first order linear homogeneous set-valued differential equations
Математичні СтудіїThe paper presents various derivatives of set-valued mappings, their main properties and how they are related to each other. Next, we consider Cauchy problems with linear homogeneous set-valued differential equations with different types of derivatives ...

Attractive Points and Convergence Theorems of (α,β)－Generalized Hybrid Set valued Mappings
Journal of Harbin University of Science and Technology, 2019 Set-valued mapping theory，which is widely used in control theory, optimization theory, mathematical economics and other fields，has developed rapidly in recent decades and has now become an important component of nonlinear analysis. Therefore, research on
