This paper deals with a study of the rate of approximation by polynomials of total degree in terms of the norm of where is the simplex Direct and converse results are achieved relating to the operators and corresponding -functionals, where and are the edges of For the special case that is the triangle somewhat weaker results were recently achieved in Feng et al. (2019).

本文研究了 总次数的多项式近似率 就...的规范而言 哪里 是单纯形 获得直接和相反的结果 给运营商 和对应的 功能,在哪里 和 是的边缘 对于特殊情况 是三角形,最近在Feng等人的研究中取得了较弱的结果。(2019)。
