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…

Orbits and characters associated with rook placements for Sylow $p$ -subgroups of finite orthogonal groups

Mikhail Ignatev, Mikhail Venchakov

Let $U$ be a Sylow $p$ -subgroup in a classical group over a finite field of characteristic $p$ . The coadjoint orbits of the group $U$ play the key role in the description of irredu…
