Approximations by multivariate sublinear and Max-product operators under convexity

Demonstratio Mathematica, 2018
Here we search quantitatively under convexity the approximation of multivariate function by general multivariate positive sublinear operators with applications to multivariate Max-product operators.

On generalized Baskakov-Durrmeyer-Stancu type operators [PDF]

, 2017
In this paper, we study some local approximation properties of generalized Baskakov-Durrmeyer-Stancu operators. First, we establish a recurrence relation for the central moments of these operators, then we obtain a local direct result in terms of the ...

Composition of some positive linear integral operators

Demonstratio Mathematica
This article is devoted to constructing sequences of integral operators with the same Voronovskaja formula as the generalized Baskakov operators, but having different behavior in other respects.

Approximation Properties Variant of Baskakov–Schurer–Szász Operators Induced by Sheffer Polynomials

Mathematics
This paper introduces a new class of Baskakov–Schurer–Szász operators generated by Sheffer polynomials in a special case. We establish a Korovkin-type theorem for these operators and investigate their uniform convergence and error estimates using the ...

Direct and Inverse Approximation Theorems for Baskakov Operators with the Jacobi-Type Weight

Abstract and Applied Analysis, 2011
We introduce a new norm and a new K-functional Kφλ(f;t)w,λ. Using this K-functional, direct and inverse approximation theorems for the Baskakov operators with the Jacobi-type weight are obtained in this paper.

On approximation properties of α-Baskakov-Schurer-Stancu operators: graphical investigations

Journal of Inequalities and Applications
This paper deals with some behavior of Baskakov-Schurer-Stancu type operators in approximating functions, grounded on non-negative parameter α. Firstly, we establish some needed moment estimations.

Some remarks about the convergence of composition operators

Journal of Inequalities and Applications
This article presents a new sequence of positive linear operators that results from recent advancements in the area of composition operators. We introduce the moment-generating function and utilize it to compute moments of certain orders.

Approximation by new Baskakov operators

Gulf Journal of Mathematics
In this paper, we discuss a uniform convergence and the error estimate for the second-order Baskakov operator with the maximal function of the Lipschitz type. A new type of Baskakov-type operator is constructed. We present some results on the convergence rate and Voronovskaja theorem of the new operator.
