초록

In the present paper we consider an integral modification of the Baskakov operators,which have weight functions of Sz´asz basis functions. We study the rate of convergence for absolutely continuous functions having a derivative coinciding a.e. with a function of bounded variation. We also mention some of the improvements of the paper [1].
