Abstract

In this paper, by using regular summability methods we modify the Bernstein–Chlodovsky operators in order get more general and powerful results than the classical aspects. We study Korovkin-type approximation theory on weighted spaces. As a special case, it is possible to Cesàro approximate (arithmetic mean convergence) to the test function e2(x)=x2 although it fails for the classical Bernstein–Chlodovsky operators. At the end of the paper, we extend our results to the multi-dimensional case.

Bernstein-Chlodovsky 算子近似中的一般可和性方法

摘要

在本文中,通过使用常规可和性方法,我们修改了 Bernstein-Chlodovsky 算子,以获得比经典方面更通用和更强大的结果。我们研究加权空间上的 Korovkin 型逼近理论。作为一种特殊情况,可以将 Cesàro 逼近(算术平均收敛)到测试函数电子2(X)=X2尽管它对于经典的 Bernstein-Chlodovsky 算子失败了。在论文的最后,我们将结果扩展到多维情况。
