Donna Q. J. Dou, Robert L. Tang, Ronald C. King

摘要:

蜂巢模型是一种组合装置,可用于确定Littlewood-Richardson系数并研究其性质。它代表了Littlewood-Richardson规则的另一种用法。在这里,蜂巢的性质被用来确定所有可能的多重性自由舒尔函数的产品和斜舒尔函数的扩展。这证实了Stembridge、Gutschwager、Thomas和Yong的结果,揭示了无多重性条件的组合起源,并说明了蜂巢模型的一些关键特征和力量。

英文摘要:

The hive model is a combinatorial device that may be used to determine Littlewood-Richardson coefficients and study their properties. It represents an alternative to the use of the Littlewood-Richardson rule. Here properties of hives are used to determine all possible multiplicity-free Schur function products and skew Schur function expansions. This confirms the results of Stembridge, Gutschwager, and Thomas and Yong, and sheds light on the combinatorial origin of the conditions for being multiplicity-free, as well as illustrating some of the key features and power of the hive model.
