Higher Order Approximation of Functions by Modified Goodman-Sharma Operators

Classical Analysis and ODEs 2024-11-25 v2

Abstract

Here we study the approximation properties of a modified Goodman-Sharma operator recently considered by Acu and Agrawal in 2019. This operator is linear but not positive. It has the advantage of a higher order of approximation of functions compared with the Goodman-Sharma operator. We prove direct and strong converse theorems in terms of a related K-functional.
