我们引入了Lascoux和Schützenberger的plastic幺半群的移位模拟,移位plastic幺半群。它可以用两种不同的方式定义:通过移动的Knuth关系,或使用Haiman的混合插入。应用包括:一个新的组合推导(和一个新版本)移位Littlewood-Richardson规则; Schur P-函数的Schur展开系数的类似结果;一个移位对应的Lascoux-Schützenberger理论的非交换Schur函数在plastic变量;一个表征移位表字;等等。
We introduce a shifted analog of the plactic monoid of Lascoux and Schützenberger, the shifted plactic monoid. It can be defined in two different ways: via the shifted Knuth relations, or using Haiman’s mixed insertion. Applications include: a new combinatorial derivation (and a new version of) the shifted Littlewood–Richardson Rule; similar results for the coefficients in the Schur expansion of a Schur P-function; a shifted counterpart of the Lascoux–Schützenberger theory of noncommutative Schur functions in plactic variables; a characterization of shifted tableau words; and more.
