移位表切换与移位Littlewood-Richardson系数

Shifted tableau switchings and shifted Littlewood-Richardson coefficients

Seung-Il Choi, Sun-Young Nam, Young-Tak Oh

摘要:

我们提供了两个移位的类似物的表切换过程由于Benkart,Sottile,和Stroomer,移位表切换过程和修改的移位表切换过程。它们是通过应用一系列被称为{ \em开关}的特殊设计的初等变换来执行的,并且具有一些引人注目的特性。例如,从这些算法中导出的映射是对合的,并且对于其阅读词满足晶格性质的移位Young tableaux表现得非常好。作为应用,我们给出了Schur $P$ -和$Q$ -函数恒等式的组合解释.我们还证明了移位表切换过程和移位$J$ -操作由于Worley之间的关系。

英文摘要:

We provide two shifted analogues of the tableau switching process due to Benkart, Sottile, and Stroomer, the shifted tableau switching process and the modified shifted tableau switching process. They are performed by applying a sequence of specially contrived elementary transformations called {\em switches} and turn out to have some spectacular properties. For instance, the maps induced from these algorithms are involutive and behave very nicely with respect to shifted Young tableaux whose reading words satisfy the lattice property. As an application, we give combinatorial interpretations of Schur $P$- and $Q$-function identities. We also demonstrate the relationship between the shifted tableau switching process and the shifted $J$-operation due to Worley.
