摘要

本文考虑Baskakov算子的一种新的局部化算子,获得了该算子的一些收敛性质.另外,利用概率论中心极限定理,建立了Baskakov算子核的新估计

Abstract

We consider a new form of the localized Baskakov operators, and obtain some convergence properties of the new operators. We also obtain a new estimate for the kernel of the Baskakov operators by making use of one of the central limit theorems in probability theory.
