A supercharacter theory for the Sylow p-subgroups of the finite symplectic and orthogonal groups

Carlos A. M. Andre, Ana Margarida Neto

We define the superclasses for a classical finite unipotent group $U$ of type $B_n(q)$, $C_n(q)$, or $D_n(q)$, and show that, together with the supercharacters defined in a p…
