关于积分型Meyer-Knig和Zeller算子的一致逼近

UNIFORM APPROXIMATION BY INTEGRAL TYPE Meyer-Knig AND Zeller OPERATORS

借助于一类K—泛函和加权光滑模之间的等价关系,给出了积分型Meyer-Konig和Zeller算子在一致逼近意义的特征刻划.

The characterization of integral type Meyer-Konig and Zeller operators in view of the equivalence between K-functiona! and weighted moduli of smoothness in uniform approximation was revealed, and a two-dimensional Meyer-Konig and Zeller type operators were introduced and the characterization of them in uniform appoximation was obtained.
