Jucys-Murphy元与S的一个恒等式的组合证明克罗夫

Jucys-Murphy Elements and a Combinatorial Proof of an Identity of S. Kerov

Jennifer R. Galovich

摘要:

考虑由R_{j} = Sigma_{i=1} ^{j-1}(ij)给出的群代数CS_{n}的元素,其中2<=j<=n。Jucys [3 - 5]和Murphy[7]证明了这些元素对角地作用在S_{n}的元素上,并给出了对角元素的显式公式。根据已故的S。Kerov,我们给出了一个组合的证明,这项工作的情况下,j=n,并提出了几个类似的结果,从这些组合的方法。

英文摘要:

Consider the elements of the group algebra CS_{n} given by R_{j}=Sigma_{i=1}^{j-1}(ij), for 2<=j<=n. Jucys [3 - 5] and Murphy[7] showed that these elements act diagonally on elements of S_{n} and gave explicit formulas for the diagonal entries. As requested by the late S. Kerov, we give a combinatorial proof of this work in case j=n and present several similar results which arise from these combinatorial methods.
