On Approximation in Ba Spaces for Generalized Kantorovich Operator

利用Ditzian-Totik光滑模,研究了推广的Kantorovich算子在Ba空间中的逼近,得到逼近的正定理与等价定理.所得结果改进、推广和统一了一些作者的结果.

In this paper,we use Ditzian-Totik modulus to study the approximation problem by the generalized Kantorovich Operator in Ba Spaces,and obtain the direct theorem and the equivalent theorem of the approximation by the generalized Kantorovich Operator in Ba Spaces. The results presented in this paper improve, extend and unify many author＇s recent results.
