Abstract Weyl-type theorems [PDF]

open access: yesMathematica Bohemica, 2016
In this paper, we give a new approach to the study of Weyl-type theorems. Precisely, we introduce the concepts of spectral valued and spectral partitioning functions.

On a Method of Solving Some Functional Equations for Set-Valued Functions

open access: yes, 2019
In the first part of the paper we collect and prove several properties of the Hausdorff metric and the Hukuhara difference. They are applied in the next part where a tool for solving several equations for set-valued functions is described.

Markov set-valued functions and their inverse limits

open access: yesTopology and its Applications, 2018
In this paper we introduce the definition of a Markov set-valued function and show that the inverse limits of two similar Markov set-valued functions are homeomorphic. This generalizes results of S. Holte, I. Banic, M. Crepnjak, and T. Lunder.

Cauchy Integral and Boundary Value for Vector-Valued Tempered Distributions

open access: yesAxioms, 2022
Using the historically general growth condition on scalar-valued analytic functions, which have tempered distributions as boundary values, we show that vector-valued analytic functions in tubes TC=Rn+iC obtain vector-valued tempered distributions as ...

Interpolation of set-valued functions

open access: yesIMA Journal of Numerical Analysis
Abstract Given a finite number of samples of a continuous set-valued function F, mapping an interval to compact subsets of the real line, we develop good approximations of F, which can be computed efficiently. In the first stage, we develop an efficient algorithm for computing an interpolant to $F$, inspired by the ‘metric polynomial ...

Lacunary Statistical Convergence in Measure for Double Sequences of Fuzzy Valued Functions

open access: yesJournal of Mathematics, 2021
Based on the concept of lacunary statistical convergence of sequences of fuzzy numbers, the lacunary statistical convergence, uniformly lacunary statistical convergence, and equi-lacunary statistical convergence of double sequences of fuzzy-valued ...

The Score, Accuracy, and Certainty Functions determine a Total Order on the Set of Neutrosophic Triplets (T, I, F) [PDF]

open access: yesNeutrosophic Sets and Systems, 2020
In this paper we prove that the Single-Valued (and respectively Interval-Valued, as well as Subset-Valued) Score, Accuracy, and Certainty Functions determine a total order on the set of neutrosophic triplets (T, I, F).

Shannon’s Sampling Theorem for Set-Valued Functions with an Application

open access: yesMathematics
In this study, we defined a kind of Fourier expansion of set-valued square-integrable functions. In fact, we have seen that the classical Fourier basis also constitutes a basis for the Hilbert quasilinear space L2(−π,π,Ω(C)) of Ω(C)-valued square ...

Boolean Valued Representation of Random Sets and Markov Kernels with Application to Large Deviations

open access: yesMathematics, 2020
We establish a connection between random set theory and Boolean valued analysis by showing that random Borel sets, random Borel functions, and Markov kernels are respectively represented by Borel sets, Borel functions, and Borel probability measures in a
