一类Lupas－Baskakov积分算子的点态逼近阶

On the Rate of Convergence of the Generalized Lupas-Baskakov Integral Operator

引入一类Ｌｕｐａｓ－Ｂａｓｋａｋｏｖ积分算子，给出它对有界变差函数的点态逼近度，并指出精确的逼近阶．

In this paper,the generalized Lupas-Baskakov Integral operator is introduced and the rate of Convergence for Bounded variation function is obtained.
