On the Approximation Properties of q−Analogue Bivariate λ‐Bernstein Type Operators

open access: yesJournal of Function Spaces, Volume 2020, Issue 1, 2020., 2020
In this article, we establish an extension of the bivariate generalization of the q‐Bernstein type operators involving parameter λ and extension of GBS (Generalized Boolean Sum) operators of bivariate q‐Bernstein type. For the first operators, we state the Volkov‐type theorem and we obtain a Voronovskaja type and investigate the degree of approximation

On Sequences of J. P. King‐Type Operators

open access: yesJournal of Function Spaces, Volume 2019, Issue 1, 2019., 2019
This survey is devoted to a series of investigations developed in the last fifteen years, starting from the introduction of a sequence of positive linear operators which modify the classical Bernstein operators in order to reproduce constant functions and x2 on [0,1]. Nowadays, these operators are known as King operators, in honor of J. P.

About Some Linear Operators

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2007, Issue 1, 2007., 2007
Using the method of Jakimovski and Leviatan from their work in 1969, we construct a general class of linear positive operators. We study the convergence, the evaluation for the rate of convergence in terms of the first modulus of smoothness and we give a Voronovskaja‐type theorem for these operators.

On matrix convexity of the Moore‐Penrose inverse

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 19, Issue 4, Page 707-710, 1996., 1995
Matrix convexity of the Moore‐Penrose inverse was considered in the recent literature. Here we give some converse inequalities as well as further generalizations.

Virial theorem in clusters of galaxies with MOND [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2022
A specific modification of Newtonian dynamics known as MOND has been shown to reproduce the dynamics of most astrophysical systems at different scales without invoking non-baryonic dark matter (DM).
