Decomposition Integrals of Set-Valued Functions Based on Fuzzy Measures [PDF]

open access: yesMathematics, 2023
The decomposition integrals of set-valued functions with regards to fuzzy measures are introduced in a natural way. These integrals are an extension of the decomposition integral for real-valued functions and include several types of set-valued integrals,

Selection Properties and Set-Valued Young Integrals of Set-Valued Functions [PDF]

open access: yesResults in Mathematics, 2020
AbstractThe paper deals with some selection properties of set-valued functions and different types of set-valued integrals of a Young type. Such integrals are considered for classes of Hölder continuous or with bounded Young p-variation set-valued functions.

Strong m-Convexity of Set-Valued Functions

open access: yesAnnales Mathematicae Silesianae, 2023
In this research we introduce the concept of strong m-convexity for set-valued functions defined on m-convex subsets of real linear normed spaces, a variety of properties and examples of these functions are shown, an inclusion of Jensen type is also ...

Set-Valued $$\alpha $$-Fractal Functions

open access: yesConstructive Approximation, 2023
In this paper, we introduce the concept of the $\alpha$-fractal function and fractal approximation for a set-valued continuous map defined on a closed and bounded interval of real numbers. Also, we study some properties of such fractal functions. Further, we estimate the perturbation error between the given continuous function and its $\alpha$-fractal ...

On a Certain Generalized Functional Equation for Set-Valued Functions

open access: yesMathematics, 2020
The aim of the paper is to generalize results by Sikorska on some functional equations for set-valued functions. In the paper, a tool is described for solving a generalized type of an integral-functional equation for a set-valued function F:X→cc(Y ...

Set-Valued T-Translative Functions and Their Applications in Finance

open access: yesMathematics, 2021
A theory for set-valued functions is developed, which are translative with respect to a linear operator. It is shown that such functions cover a wide range of applications, from projections in Hilbert spaces, set-valued quantiles for vector-valued random

Topologically Transitive and Mixing Properties of Set-Valued Dynamical Systems

open access: yesAbstract and Applied Analysis, 2021
We introduce and study two properties of dynamical systems: topologically transitive and topologically mixing under the set-valued setting. We prove some implications of these two properties for set-valued functions and generalize some results from a ...

Contributions to the theory of set valued functions and set valued measures [PDF]

open access: yesTransactions of the American Mathematical Society, 1987
Measurable multifunctions and multimeasures with values in a Banach space are studied. We start by proving a variation of the known Dunford theorem for weak compactness in

Integration of compact set-valued functions [PDF]

open access: yesPacific Journal of Mathematics, 1975
provided by applying the McShane ^-integral. This integral is a Riemann-type integral and includes the Bochner, Lebesgue and other types of integrals, and by using Riemann sums it avoids deep measure theory. Thus, the ^-integral of set-valued functions contains other types of integrals such as the Hukuhara and Debreu integrals. Generalizations of known
