Weyl轨道特征标与Schur函数

Weyl Orbit Characters and Schur Functions

H. R. Karadayi, M. Gungormez

摘要:

对于有限李代数,它表明,字符可以定义的Weyl轨道,然后为不可约表示。对于$A_N$李代数,只需声明字符等价于舒尔函数即可计算权重多重性。这也意味着计算字符不需要对Weyl群求和。然而,将显示与Weyl字符公式的兼容性。

英文摘要:

For finite Lie algebras, it is shown that characters can be defined first for Weyl orbits and then for irreducible representations. For $A_N$ Lie algebras, weight multiplicities can then be calculated by only stating that characters are equivalent to Schur functions. This also means that to calculate characters there is no need to sum over Weyl groups. The compatibility with the Weyl character formula will however be shown.
