On Bernstein-Kantorovich Operators reproducing affine functions in movable interval
摘要
In this paper, we introduce a new type of modified Bernstein-Kantorovich operators in movable interval, which reproduce affine functions. We obtain a Jackson type theorem with Ditzian-Totik type modulus of smoothness for approximation of continuous functions, and a Voronovskaja type asymptotic estimate for approximation of smooth functions.
