与萨尔问题有关的循环筛选、项链和分支规则

Cyclic sieving, necklaces, and branching rules related to Thrall's problem

Connor Ahlbach, Joshua P. Swanson

摘要:

我们发现,循环筛选现象的Reiner-斯坦顿-白与项链产生的功能所产生的Klyachko的工作提供了一个非常统一的,直接的,主要是双射的方法,一系列的结果,由于Kraskiewicz-韦曼,Stembridge,和Schocker有关的所谓的高李模和分支规则的夹杂物$ C_a \wr S_b \hookrightarrow S_{ab} $。扩展的方法给出单项式扩展某些分级Frobenius系列所产生的一个推广的萨尔的问题。

英文摘要:

We show that the cyclic sieving phenomenon of Reiner--Stanton--White together with necklace generating functions arising from work of Klyachko offer a remarkably unified, direct, and largely bijective approach to a series of results due to Kraskiewicz--Weyman, Stembridge, and Schocker related to the so-called higher Lie modules and branching rules for inclusions $ C_a \wr S_b \hookrightarrow S_{ab} $. Extending the approach gives monomial expansions for certain graded Frobenius series arising from a generalization of Thrall's problem.
