Convergence of λ-Bernstein operators based on (p, q)-integers [PDF]
Journal of Inequalities and Applications, 2020 AbstractIn the present paper, we construct a new class of positive linearλ-Bernstein operators based on (p,q)-integers. We obtain a Korovkin type approximation theorem, study the rate of convergence of these operators by using the conception ofK-functional and moduli of continuity, and also give a convergence theorem for the Lipschitz continuous ...

Advanced Electronic Materials, 2022 The single crystal growth of Mg3Bi2‐based thermoelectric materials is of great significance for their applications near room temperature. So far, it is still a big challenge to grow such bulk single crystals and attempts are primarily focused on the ...

Some approximation results on Bernstein-Schurer operators defined by ( p , q ) $(p,q)$ -integers [PDF]
Journal of Inequalities and Applications, 2015 Recently, Mursaleen et al. (On $(p,q)$ -analogue of Bernstein operators, arXiv:1503.07404 ) introduced and studied the $(p,q)$ -analog of Bernstein operators by using the idea of $(p,q)$ -integers. In this paper, we generalize the q-Bernstein-Schurer operators using $(p,q)$ -integers and obtain a Korovkin type approximation theorem.

On wavelets Kantorovich ( p , q ) $(p,q)$ -Baskakov operators and approximation properties
Journal of Inequalities and Applications, 2023 In this paper, we generalize and extend the Baskakov-Kantorovich operators by constructing the ( p , q ) $(p, q)$ -Baskakov Kantorovich operators ( ϒ n , b , p , q h ) ( x ) = [ n ] p , q ∑ b = 0 ∞ q b − 1 υ b , n p , q ( x ) ∫ R h ( y ) Ψ ( [ n ] p , q ...

Bootstrap for integer‐valued GARCH(p, q) processes [PDF]
Statistica Neerlandica, 2021 AbstractWe consider integer‐valued processes with a linear or nonlinear generalized autoregressive conditional heteroscedastic models structure, where the count variables given the past follow a Poisson distribution. We show that a contraction condition imposed on the intensity function yields a contraction property of the Markov kernel of the process.

On fractional (p,q) $(p,q)$-calculus
Advances in Difference Equations, 2020 In this paper, the new concepts of (p,q) $(p,q)$-difference operators are introduced. The properties of fractional (p,q) $(p,q)$-calculus in the sense of a (p,q) $(p,q)$-difference operator are introduced and developed.

Journal of Inequalities and Applications, 2021 In this paper, we study generalizations of some integral inequalities related to Hardy type integral inequalities via ( p , q ) $(p, q)$ -calculus. Many results obtained in this paper provide extensions of existing results in the literature. Furthermore,

Bivariate-Schurer-Stancu operators based on (p,q)-integers
Filomat, 2018 The aim of this article is to introduce a bivariate extension of Schurer-Stancu operators based on (p,q)-integers. We prove uniform approximation by means of Bohman-Korovkin type theorem, rate of convergence using total modulus of smoothness and degree of approximation via second order modulus of smoothness, Peetre?s K-functional, Lipschitz

Tikrit Journal of Pure Science, 2023 In this paper we generalize the Fuglede-Putnam theorem to non-normal operators to posinormal operator and co-posinormal operators. Also we prove this theorem to supra class posinormal operators (called supraposinormal operator) and co-supra class ...
