Set-valued mapping and Rough Probability [PDF]

open access: yesMathematical Sciences Letters, 2017
In 1982, the theory of rough sets proposed by Pawlak and in 2013, Luay concerned a rough probability by using the notion of Topology. In this paper, we study the rough probability in the stochastic approximation spaces by using set-valued mapping and ...

Decompositions of set-valued mappings [PDF]

open access: yesAlgebra and Discrete Mathematics, 2020
Let X be a set, BX denotes the family of all subsets of X and F:X→BX be a set-valued mapping such that x∈F(x), supx∈X|F(x)|<κ, supx∈X|F−1(x)|<κ for all x∈X and some infinite cardinal κ. Then there exists a family F of bijective selectors of F such that |F|<κ and F(x)={f(x):f∈F} for each x∈X.

New Generalizations of Set Valued Interpolative Hardy-Rogers Type Contractions in b-Metric Spaces

open access: yesJournal of Function Spaces, 2021
Debnath and De La Sen introduced the notion of set valued interpolative Hardy-Rogers type contraction mappings on b-metric spaces and proved that on a complete b-metric space, whose all closed and bounded subsets are compact, the set valued interpolative

An inverse mapping theorem for set-valued maps [PDF]

open access: yesProceedings of the American Mathematical Society, 1994
We prove that certain Lipschitz properties of the inverse F − 1 {F^{ - 1}} of a set-valued map F are inherited by the map ( f + F ) − 1 {(f + F)^{ - 1}} when f ...

The Tikhonov Regularization Method for Set-Valued Variational Inequalities

open access: yesAbstract and Applied Analysis, 2012
This paper aims to establish the Tikhonov regularization theory for set-valued variational inequalities. For this purpose, we firstly prove a very general existence result for set-valued variational inequalities, provided that the mapping involved has ...

A Steepest Descent Method for Set Optimization Problems with Set-Valued Mappings of Finite Cardinality [PDF]

open access: yesJournal of Optimization Theory and Applications, 2021
In this paper, we study a first-order solution method for a particular class of set optimization problems where the solution concept is given by the set approach.

Stability for a Class of Differential Set-Valued Inverse Variational Inequalities in Finite Dimensional Spaces

open access: yesAxioms, 2022
In this paper, we introduce and study a new class of differential set-valued inverse variational inequalities in finite dimensional spaces. By applying a result on differential inclusions involving an upper semicontinuous set-valued mapping with closed ...

Several Theorems on Single and Set-Valued Prešić Type Mappings

open access: yesMathematics, 2020
In this study, we introduce set-valued Prešić type almost contractive mapping, Prešić type almost F-contractive mapping and set-valued Prešić type almost F-contractive mapping in metric space and prove some fixed point results for these mappings ...

Roughness in Membership Continuous Function

open access: yesمجلة المختار للعلوم, 2021
In this paper, we introduce the new definition of rough membership function using continuous function and we discuss several concepts and properties of rough continuous set value functions as new results on rough continuous function and membership ...

Fixed Point Theorem for Set Valued Mapping with Rational Condition

open access: yes, 2020
In this paper, we generalized the principle of Banach contractive to the relative formula and then used this formula to prove that the set valued mapping has a fixed point in a complete partial metric space. We also showed that the set-valued mapping can
