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

Abstract

A new Goodman-Sharma modification of the Baskakov operator is presented for approximation of bounded and continuous on $[0,\,\infty)$ functions. In our study on the approximation error of the proposed operator we prove direct and strong converse theorems with respect to a related K-functional. This operator is linear but not positive. However it has the advantage of a higher order of approximation compared to the Goodman-Sharma variant of the Baskakov operator defined in 2005 by Finta.
