Supershift properties for nonanalytic signals. [PDF]

open access: yesNanophotonics
Abstract The phenomenon of superoscillations is of great interest in microscopy, antenna design, and material sciences. This phenomenon has been generalized and has given rise to the concept of supershift, which is a far reaching extension that applies to functions that may present discontinuous derivatives. From this perspective, this is a notion that

Multivariate weighted kantorovich operators

open access: yesMathematical Foundations of Computing, 2020
Herein, the authors introduce a class of multidimensional weighted Kantorovich operators \(K_n\), \(n\geq 1\), whose definition is given on the space of continuous functions \(C(Q_{d})\) (where \(Q_d\) is the \(d\)-dimensional hypercube \([0,1]^{d}\), \(d\geq 1\)), and it involves the well-known Bernstein polynomials.

Generalization of Szász operators: quantitative estimate and bounded variation

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2021
Difference of exponential type Szász and Szász-Kantorovich operators is obtained. Similar estimates are given for higher order $\mu$-derivatives of the Szász operators and the Szász-Kantorovich type operators acting on the same order $\mu$-derivative of ...

Approximation results for a general class of Kantorovich type operators [PDF]

open access: yes, 2014
We introduce and study a family of integral operators in the Kantorovich sense for functions acting on locally compact topological groups. We obtain convergence results for the above operators with respect to the pointwise and uniform convergence and in ...

Generalizing the Kantorovich Metric to Projection-Valued Measures [PDF]

open access: yes, 2016
Given a compact metric space $X$, the collection of Borel probability measures on $X$ can be made into a compact metric space via the Kantorovich metric. We partially generalize this well known result to projection-valued measures. In particular, given a

Estimates for Tsallis relative operator entropy [PDF]

open access: yes, 2017
We give the tight bounds of Tsallis relative operator entropy by using Hermite-Hadamard's inequality. Some reverse inequalities related to Young inequalities are also given.

Revisiting Kantorovich Operators in Lebesgue Spaces

open access: yesJournal of the Indonesian Mathematical Society, 2023
According to the Weierstrass Approximation Theorem, any continuous function on the closed and bounded interval can be approximated by polynomials. A constructive proof of this theorem uses the so-called Bernstein polynomials. For the approximation of integrable functions, we may consider Kantorovich operators as certain modifications for Bernstein ...
