行严格拟对称Schur函数的Littlewood-Richardson型定则

A Littlewood-Richardson Type Rule for Row-Strict Quasisymmetric Schur Functions

Jeffrey Ferreira

摘要:

给出了行严格拟对称Schur函数与对称Schur函数乘积关于行严格拟对称Schur函数展开的Littlewood-Richardson型规则。这种扩展来自Mason和Remmel(2010)定义的插入算法的几个新性质,该算法将正整数插入到行严格组合表中。

英文摘要:

We give a Littlewood-Richardson type rule for expanding the product of a row-strict quasisymmetric Schur function and a symmetric Schur function in terms of row-strict quasisymmetric Schur functions. This expansion follows from several new properties of an insertion algorithm defined by Mason and Remmel (2010) which inserts a positive integer into a row-strict composition tableau.
