对称群特征标的亏损
Defect of characters of the symmetric group
摘要:
在B. Kuelshammer,J. B. Olsson和G. R. Robinson关于对称群的广义块的定义,给出了对称群S_n的特征标的\ell -亏损的定义,其中\ell > 1是任意整数.我们证明了\ell -亏损是由钩长公式的一个类似物给出的,并利用它证明了当n < \ell^2时S_n中McKay猜想的一个\ell -版本.
英文摘要:
Following the work of B. Kuelshammer, J. B. Olsson and G. R. Robinson on generalized blocks of the symmetric groups, we give a definition for the \ell-defect of characters of the symmetric group S_n, where \ell > 1 is an arbitrary integer. We prove that the \ell -defect is given by an analogue of the hook-length formula, and use it to prove, when n < \ell^2, an \ell-version of the McKay Conjecture in S_n .
