Simultaneous Approximation by Beta Operators for Functions Whose Derivatives Have only Discontinuity Points of the First Kind

摘要/Abstract

摘要:

利用概率论中中心极限定理研究了Beta算子及其导数对导数只具有第1类间断点函数类的同时逼近问题,得到了误差的点态的估计.

Abstract:

By using the central limit theorem in probability theory,the problem of simultaneous approximation is investigated by Beta operators and its derivatives for functions whose derivatives have only discontinuity points of the first kind,the pointwise result of the error is obtained.
