一种Bernstein-Stancu算子的 Kantorovich型变形算子的逼近

摘要

针对.Ic，¨oz介绍的一种Bernstein‐Stancu算子的 Kantorovich型变形算子，建立了该算子的逼近的点态估计和正、逆定理，并利用函数的光滑性进一步考虑了该算子的推广形式的逼近．%Aiming at a Kantorovich‐type variant of Bernstein‐stancu operators introduced by .Ic,¨oz ,this paper establishes the pointwise estimation as well as direct and inverse theorems of the approximation of the operators , and the popularization form approximation of the operators by the smoothness of functions .
