关于超群及其半简化表示范畴
On supergroups and their semisimplified representation categories
摘要:
超群概型$G$的表示范畴$\mathcal{A} = Rep(G,ε)$有一个最大的真张量理想,即可忽略态射的理想$\mathcal{N}$。如果我们将$\mathcal{A}$除以$\mathcal{N}$,我们就会得到亲约化超群方案$G^{red}$的半单表示范畴。我们列出了它的一些属性,并确定$G^{red}$的情况下$GL(m|1)$。
英文摘要:
The representation category $\mathcal{A} = Rep(G,ε)$ of a supergroup scheme $G$ has a largest proper tensor ideal, the ideal $\mathcal{N}$ of negligible morphisms. If we divide $\mathcal{A}$ by $\mathcal{N}$ we get the semisimple representation category of a pro-reductive supergroup scheme $G^{red}$. We list some of its properties and determine $G^{red}$ in the case $GL(m|1)$.
