Approximation properties of modified (p, q)-Szász-Mirakyan-Kantorovich operators
AIMS Mathematics, 2020 In this paper, we introduce a new kind of modified (p, q)-Szász-Mirakyan-Kantorovich operators based on (p, q)-calculus. Next, the moments computation formulas, the second and fourth order central moments computation formulas and other quantitative ...

The Voronovskaja type theorem for an extension of Szász-Mirakjan operators
Demonstratio Mathematica, 2012 Abstract Recently, C. Mortici defined a class of linear and positive operators depending on a certain function ϕ, which generalize the well known Szász-Mirakjan operators. For these generalized operators we establish a Voronovskaja type theorem, the uniform convergence and the order of approximation, using the modulus of continuity.

International Journal of Mathematics and Mathematical Sciences, 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

Convergence and Voronovskaja-type theorems for derivatives of generalized Baskakov operators
Central European Journal of Mathematics, 2008 The authors prove some theorems the convergence of the first derivatives of generalized Baskakov operators for functions of one and two variables in polynomial and exponential weight spaces. Some Voronovskaja-type theorems are also presented.

A Voronovskaja-Type Theorem for a Kind of Durrmeyer-Bernstein-Stancu Operators
Gazi University Journal of Science, 2019 In this paper, we study on a Durrmeyer variant of Bernstein-Stancu operators. We give a Voronovskaja-type theorem for these type operators.

Approximation by bivariate generalized Bernstein–Schurer operators and associated GBS operators
Advances in Difference Equations, 2020 We construct the bivariate form of Bernstein–Schurer operators based on parameter α. We establish the Voronovskaja-type theorem and give an estimate of the order of approximation with the help of Peetre’s K-functional of our newly defined operators ...

Quadrature rules associated with Baskakov quasi-interpolants
, 2014 Quadrature rules on the positive real half-line obtained by integrating the Baskakov quasi-interpolants described in \cite{MM, Sab7} are constructed and their asymptotic convergence orders are studied.
