Bernstein多项式线性组合的逼近阶

Approximation Order for Combinations of Bernstein Polynomials

本文对于Ｂｅｒｎｓｔｅｉｎ多项式线性组合，考虑了区间［０，１］端点附近的逼近情况，建立了点态的逼近定理。

The author studies the approximation on the neighburhood of two endpoints of the interval[0,1] for linear combinations of Bernstein polynomials,and gives a pointwise approximation the-orem,improving the result in [1].
