The approximation of bivariate functions by bivariate operators and GBS operators

open access: yesJournal of Numerical Analysis and Approximation Theory, 2011
In this paper we demonstrate a general approximation theorem for the bivariate functions by bivariate operators and GBS (Generalized Boolean Sum) operators.

On a New Modification of Baskakov Operators with Higher Order of Approximation

open access: yesMathematics
A new Goodman–Sharma-type modification of the Baskakov operator is presented for approximation of bounded and continuous functions on [0,∞). We study the approximation error of the proposed operator.

Hardy-Littlewood-Sobolev Theorem for Bourgain-Morrey Spaces and Approximation

open access: yesEuropean Journal of Mathematical Analysis
In this paper, we establish an extension of the Hardy-Littlewood-Sobolev theorem to the setting of the Bourgain-Morrey space Mαq,p(Rd) (1 ≤ q, p, α ≤ ∞), which theory goes back to Bourgain in 1991.
