Complete Convergence for Weighted Sums of Widely Acceptable Random Variables under Sublinear Expectations

open access: yesDiscrete Dynamics in Nature and Society, 2021
Using different methods than the probability space, under the condition that the Choquet integral exists, we study the complete convergence theorem for weighted sums of widely acceptable random variables under sublinear expectation space.

A numerical method for solving a complete hypersingular integral equation of the second kind and its justification

open access: yesMathematical Modelling and Analysis, 2023
A complete hypersingular integral equation of the second kind was obtained as a boundary integral equation for the diffraction and scattering problem of electromagnetic waves in space separated by the periodically placed non-perfectly conducting strips.

Unified Convergence Criteria for Iterative Banach Space Valued Methods with Applications

open access: yesMathematics, 2021
A plethora of sufficient convergence criteria has been provided for single-step iterative methods to solve Banach space valued operator equations. However, an interesting question remains unanswered: is it possible to provide unified convergence criteria

Alternating direction implicit method for poisson equation with integral conditions

open access: yesMathematical Modelling and Analysis, 2023
In this paper, we investigate the convergence of the Peaceman-Rachford Alternating Direction Implicit method for the system of difference equations, approximating the two-dimensional elliptic equations in rectangular domain with nonlocal integral ...

Modified Bernstein–Durrmeyer Type Operators

open access: yesMathematics, 2022
We constructed a summation–integral type operator based on the latest research in the linear positive operators area. We establish some approximation properties for this new operator.

Iterating Fixed Point via Generalized Mann’s Iteration in Convex b-Metric Spaces with Application

open access: yesComplexity, 2021
This manuscript investigates fixed point of single-valued Hardy-Roger’s type F-contraction globally as well as locally in a convex b-metric space. The paper, using generalized Mann’s iteration, iterates fixed point of the abovementioned contraction ...

Improved Iterative Solution of Linear Fredholm Integral Equations of Second Kind via Inverse-Free Iterative Schemes

open access: yesMathematics, 2020
This work is devoted to Fredholm integral equations of second kind with non-separable kernels. Our strategy is to approximate the non-separable kernel by using an adequate Taylor’s development. Then, we adapt an already known technique used for separable

On integration with respect to filter

open access: yesVisnik Harkivsʹkogo Nacionalʹnogo Universitetu im. V.N. Karazina. Cepiâ Matematika, Prikladna Matematika i Mehanika, 2023
This article is devoted to the study of one generalization of the Riemann integral. Namely, in the paper, it was observed that the classical definition of the Riemann integral over a finite segment as a limit of integral sums, when the diameter of the ...
