摘要
该文讨论了单纯形上Meyer- Konig and Zeller算子的矩量问题.首先得到了二阶矩量在广义积分下的显式表示,并由此导出了二阶矩量的二元Appell超几何函数表示,超几何级数表示和完全渐近公式.
In this paper, the explicit expressions of the second moments for the Meyer-Knig and Zeller operators on a simplex are discussed and derived in terms of the generalized integration, Appell hypergeometric functions in two variables and hypergeometric series. With that, the complete asymptotic formulae of the second moments are obtained.
