Schur $P$ -函数的多重自由展开

Multiplicity free expansions of Schur $P$-functions

Kristin M. Shaw, Stephanie van Willigenburg

摘要:

在导出Schur $P$ -函数用Schur函数展开式中系数的不等式后,我们给出了这种展开式何时是多重自由的判据.从这里我们研究了扭曲对称群的不可约自旋特征标在基本自旋特征标与对称群的不可约特征标的乘积中的重数,并确定了它何时是重数自由的.

英文摘要:

After deriving inequalities on coefficients arising in the expansion of a Schur $P$-function in terms of Schur functions we give criteria for when such expansions are multiplicity free. From here we study the multiplicity of an irreducible spin character of the twisted symmetric group in the product of a basic spin character with an irreducible character of the symmetric group, and determine when it is multiplicity free.
