Borel subgroup
WebThe character value of St on an element g equals, up to sign, the order of a Sylow subgroup of the centralizer of g if g has order prime to p, and is zero if the order of g is divisible by p.

WebProof. As a rst (crucial) step, we apply Borel’s covering theorem via Borel subgroups: there is a Borel subgroup BˆGcontaining g. The Jordan decomposition of gviewed in Bmust … WebI'd try to use the fact that if a group $G$ is acting on a set $\Omega$, then the normalizer of a subgroup $U$ acts on the set of fixed points of $U$. Here $\Omega$ is the set of flags and $U$ the Borel subgroup $B$, which has a unique fixed point, so that its normalizer has to stabilize it. – Feb 28, 2024 at 7:05 Add a comment 2 Answers Sorted by:
