摘要
本文建立了具有正核的多维卷积算子逼近的量化定理。同时得到多元Jackson多项式算子和多元Vallée Poussin多项式算子逼近的误差估计。
In this paper,the quantitative theorems on the approximation by multidimensional convolution operators are established. In particular, the degree of approximation by multivariate Jackson and Vallee Poussin polynomials is also obtained.
