一类Durrmeyer算子线性组合的加权逼近

Weighted Approximation by a Class of Combinations for Durrmeyer Operators

本文主要给出了一类Ｂｅｒｎｓｔｅｉｎ－Ｄｕｒｒｍｅｙｅｒ算子的线性组合在Ｌｐ逼近意义下加Ｊａｃｏｂｉ权逼近时的特征刻划．

In this paper we considered the weighted approximation by a class of Combinations for Bernstein Durrmeyer operators with Jacobi weights and the characterization of approximation order in Lp[0,1] are given.
