On approximation properties of some non-positive Bernstein-Durrmeyer type operators

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023
In this paper we shall introduce a new type of Bernstein Durrmeyer operators which are not positive on the entire interval [0, 1]. For these operators we will study the uniform convergence on all continuous functions on [0, 1] as well as a result given ...

Error Estimation for Shifted q‐Szász–Kantorovich Operators and Their Numerical Properties

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This paper introduces a novel class of q‐Szász–Mirakjan–Kantorovich operators defined with shifted sequences. Utilizing the basic principles of q‐calculus, we design the King‐type fundamental construction of q‐Szász–Mirakjan–Kantorovich operators and derive their moments and central moments.

Experiment on numerical conformal mapping of unbounded multiply connected domain in fundamental solutions method

International Journal of Mathematics and Mathematical Sciences, Volume 26, Issue 1, Page 55-63, 2001., 2001
We are concerned with the experiment on numerical conformal mappings. A potentially theoretical scheme in the fundamental solutions method, different from the conventional one, has been recently proposed for numerical conformal mappings of unbounded multiply connected domains.

Generalized Complex Conformable Derivative and Integral Bases in Fréchet Spaces [PDF]

Assiut University Journal of Multidisciplinary Scientific Research
This paper presents an additional approach in the field of polynomial bases, utilizing generalized complex conformable fractional derivative and integral operators. These operators are applied to polynomial bases of complex conformable derivatives (GCCDB)

Use of saline‐soaked bacterial culture swabs increases bacterial recovery in dogs with superficial bacterial folliculitis

Veterinary Dermatology, Volume 36, Issue 5, Page 621-629, October 2025.
Background – Canine superficial bacterial folliculitis (SBF) is a common recurrent condition with a growing requirement for culture and susceptibility as a consequence of increased antimicrobial resistance and antimicrobial stewardship. Different opinions persist about the ideal technique for culture sample acquisition, which varies with lesion ...

Faster approximation to multivariate functions by combined Bernstein-Taylor operators

Demonstratio Mathematica
In this article, we incorporate multivariate Taylor polynomials into the definition of the Bernstein operators to get a faster approximation to multivariate functions by these combined operators.

Quantum coherence of Gaussian states in curved spacetime

Results in Physics, 2019
We study quantum coherence of two-mode Gaussian states in the background of an asymptotically flat black hole. We find that quantum coherence between mode A observed by an inertial observer Alice and mode B observed by an accelerated Bob who hovers near ...

H∞ interpolation constrained by Beurling–Sobolev norms

Moroccan Journal of Pure and Applied Analysis, 2023
We consider a Nevanlinna–Pick interpolation problem on finite sequences of the unit disc, constrained by Beurling–Sobolev norms. We find sharp asymptotics of the corresponding interpolation quantities, thereby improving the known estimates. On our way we
