The Baskakov operators associated with are defined by
whenever the righthand side exists. The modified Baskakov operators are derived from the original ones by truncating the infinite sum depending on the value of , namely,
The modified operators become interesting if as . The authors prove that if , , for some positive and , then for any , , provided . It is well known that and the authors show that their condition is best possible in the sense that if , then for in the above class, , .
