一般线性超群的联系原理的组合性质
Combinatorial aspects of the linkage principle for general linear supergroups
摘要:
设$G=GL(m|n)$是一般线性超群,$G_{ev}$是它的偶子超群,同构于$GL(m)\times GL(n)$ .在本文中,我们使用的显式描述$G_{ev}$ -本征向量的余标准超模$\nabla(λ)$,最大的多项式$G$ -子超模的诱导超模$H^0_G(λ)$,$(m|n)$ -钩划分$λ$,和某些态射$ψ_k$的性质,以获得有关的结果,奇链接$G$上的一个域$F$的特征不同于$2$。
英文摘要:
Let $G=GL(m|n)$ be a general linear supergroup and $G_{ev}$ be its even subsupergroup isomorphic to $GL(m)\times GL(n)$. In this paper we use the explicit description of $G_{ev}$-primitive vectors in the costandard supermodule $\nabla(λ)$, the largest polynomial $G$-subsupermodule of the induced supermodule $H^0_G(λ)$, for $(m|n)$-hook partition $λ$, and a properties of certain morphisms $ψ_k$ to derive results related to the odd linkage for $G$ over a field $F$ of characteristic different from $2$.
