摘要
该文给出了一类多元Gauss-Weierstrass算子线性组合加Jacobi权在一致逼近下的正、逆定理和逼近阶的特征刻划。
The weighted approximation by a class of linear combinations of multidimensional Gauss-Weierstrass op- erators with Jacobi weight in uniform approximation is considered.The direct and converse results and the characteriza- tion of approximation order are given.
