G/P的切丛在正特征上的稳定性

Stability of the tangent bundle of G/P in positive characteristics

Indranil Biswas, Pierre-Emmanuel Chaput, Christophe Mourougane

摘要:

设$G$是特征为$p > 0$的代数闭域$k$上的几乎单单连通仿射代数群.如果$G$的类型为$B_n$、$C_n$或$F_4$,则假定为$p > 2$,如果$G$的类型为$G_2$,则假定为$p > 3$。设$P \subset G$是一个抛物子群.我们证明了$G/P$的切丛对于$G/P$上的反正则极化是Frobenius稳定的.

英文摘要:

Let $G$ be an almost simple simply-connected affine algebraic group over an algebraically closed field $k$ of characteristic $p > 0$. If $G$ has type $B_n$, $C_n$ or $F_4$, we assume that $p > 2$, and if $G$ has type $G_2$, we assume that $p > 3$. Let $P \subset G$ be a parabolic subgroup. We prove that the tangent bundle of $G/P$ is Frobenius stable with respect to the anticanonical polarization on $G/P$.
