【Abstract】 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.更多还原
