Stancu型的Durrmeyer-Schurer多项式在圆盘上的逼近

Approximation of Durrmeyer-Schurer Polynomials with Stancu Type on Disks

本文引入了一种Stancu型的Durrmeyer-Schurer多项式,估计了它在圆盘上对解析函数一直逼近,同时逼近的速度和Voronskaja型估计.

In the present paper, one Durrmeyer-Schurer polynomials with Stancu type is introduced. And the uniform approximation to analytic functions on disks is estimated, the approximation speed and Voronskaja-type results are obtained.
