变形的Meyer-Knig-Ze11er算子对有界变差函数的逼近

Approximation to functions of bounded variation by modified Meyer-K(?)nig-Zeller operators

引入了两个变形的Meyer-Knig-Zeller算子S_n(f,x)、S_n~*(f,x),研究了这两个算子对有界变差函数的逼近。

Two modified Meyer-Konig-Zeller operators----Sn(f, x) and Sn(f, x) areintroduced. The approximation to function of bounded variation by these operators is studied, the results shown
