Orbits of submaximal dimension for Sylow $p$ -subgroups of finite classical orthogonal groups

Mikhail Ignatev, Mikhail Venchakov

Let $U$ be a Sylow $p$ -subgroup in a classical orthogonal group over a finite field with $q$ elements of characteristic $p$ large enough. The coadjoint orbits of the group $U$ play…

Rook placements and coadjoint orbits for maximal unipotent subgroups of finite symplectic groups

Mikhail Venchakov

Let $U$ be a maximal unipotent subgroup in a symplectic group over a finite field of sufficiently large characteristic $p$ . According to the Kirillov's orbit method, the coadjoint…
