Estimates for the Differences of Certain Positive Linear Operators

open access: yesMathematics, 2020
The present paper deals with estimates for differences of certain positive linear operators defined on bounded or unbounded intervals. Our approach involves Baskakov type operators, the kth order Kantorovich modification of the Baskakov operators, the ...

Convergence properties of generalized Lupaş-Kantorovich operators

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2021
In the present paper, we consider the Kantorovich modification of generalized Lupaş operators, whose construction depends on a continuously differentiable, increasing and unbounded function $\rho$.

A Choquet theory of Lipschitz‐free spaces

open access: yesProceedings of the London Mathematical Society, Volume 132, Issue 2, February 2026.
Abstract Let (M,d)$(M,d)$ be a complete metric space and let F(M)$\mathcal {F}({M})$ denote the Lipschitz‐free space over M$M$. We develop a ‘Choquet theory of Lipschitz‐free spaces’ that draws from the classical Choquet theory and the De Leeuw representation of elements of F(M)$\mathcal {F}({M})$ (and its bi‐dual) by positive Radon measures on βM ...

Approximation in variation by the Kantorovich operators; pp. 201–209 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2011
We discuss the rate of approximation of the Kantorovich operators. The rate of approximation is given with respect to the variation seminorm.

The Krawczyk operator and Kantorovich's theorem

open access: yesJournal of Mathematical Analysis and Applications, 1990
The paper deals with the comparison of Kantorovich's test for the existence of a solution of a system of nonlinear equations of the form \(F(x)=0\) and a modification of Moore's existence test based on the Krawczyk operator. The modification involves a suitable slope instead of the Jacobian matrix \(F'\) and is proved to require less computational work

Asymptotic Properties for a General Class of Szász–Mirakjan–Durrmeyer Operators

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 2, Page 734-743, 30 January 2026.
ABSTRACT In this paper, we introduce a general family of Szász–Mirakjan–Durrmeyer type operators depending on an integer parameter j∈ℤ$$ j\in \mathbb{Z} $$. They can be viewed as a generalization of the Szász–Mirakjan–Durrmeyer operators, Phillips operators, and corresponding Kantorovich modifications of higher order.

Kantorovich-Schurer bivariate operators [PDF]

open access: yesMiskolc Mathematical Notes, 2004
Summary: Let \(p,q\) be two non-negative given integers. The sequence \((\tilde{K}_{m,n,p,q})_{m,n\in N}\), \(\tilde{K}_{m,n,p,q}:L_1([0,1]\times [0,1])\to C([0,1]\times[0,1])\), \[ \left(\tilde{K}_{m,n,p,q} f\right)(x,y) \] \[ = (m+p+1)(n+p+1)\times \sum\nolimits^{m+p}_{k=0}\sum\nolimits^{n+q}_{j=0} \tilde{p}_{m,k}(x)\tilde{p}_{n j}(y)\int\nolimits ...

Digital Twin‐Driven Two‐Stage Bi‐Level Collaborative Operation Strategy for Multi‐Microgrids Considering Energy Sharing and Price Incentives

open access: yesDigital Twins and Applications, Volume 3, Issue 1, January/December 2026.
ABSTRACT To enhance the techno‐economic performance and robustness of multi‐microgrids (MMG) systems, this paper proposes a two‐stage bi‐level collaborative optimisation strategy integrating energy sharing and price incentives. In the day‐ahead stage, the shared energy storage operator (SESO) at the upper level employs conditional Wasserstein ...

Statistical convergence of integral form of modified Szász–Mirakyan operators: an algorithm and an approach for possible applications

open access: yesJournal of Inequalities and Applications
In this study, we take into account the of modified Szász–Mirakyan–Kantorovich operators to obtain their rate of convergence using the modulus of continuity and for the functions in Lipschitz space.

Adaptive Multi‐Timeframe Reconfiguration of Smart Distribution Networks With Flexibility Resources Under Operational Uncertainty

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper introduces a hybrid deterministic‐stochastic framework for the multi‐timeframe reconfiguration (MTFR) of distribution networks, coordinating renewable resources and demand response under uncertainty. The proposed MTFR strategy, validated on the IEEE 33‐bus system, significantly reduces operational costs and energy losses while improving ...
