Coadjoint orbits of Row Closed Subgroups of $U_{n} (q)$

Qiong Guo, Richard Dipper

Let $n$ be a natural number, let $q$ be a prime power, and let $U_{n} (q)$ denote the group of unitriangular $n \times n$ matrices over the finite field $F_{q}$ with $q$ element…

Iwahori-Hecke algebras acting on tensor space by $q$ -deformed letter permutations and $q$ -partition algebras

Geetha Thangavelu, Richard Dipper

Let $R$ be a commutative ring with identity and let $V$ be a free $R$ -module of rank $n$ for some $n \in N$ . Fixing an $R$ -basis $E$ of $V$ , the symmetric group $\…

On coadjoint orbits for $p$ -Sylow subgroups of finite classical groups

Qiong Guo, Markus Jedlitschky, Richard Dipper

Kirillov's orbit theory provides a powerful tool for the investigation of irreducible unitary representations of many classes of Lie groups. In a previous paper we used a modificat…

Orbit method for $p$ -Sylow subgroups of finite classical groups

Qiong Guo, Markus Jedlitschky, Richard Dipper

For the $p$ -Sylow subgroups $U$ of the finite classical groups of untwisted Lie type, $p$ an odd prime, we construct a monomial $C U$ -module $M$ which is isomorphic to the…

On monomial linearisation and supercharacters of pattern subgroups

Qiong Guo, Richard Dipper

Column closed pattern subgroups $U$ of the finite upper unitriangular groups $U_{n} (q)$ are defined as sets of matrices in $U_{n} (q)$ having zeros in a prescribed set of columns beside…

$U_{n} (q)$ acting on flags and supercharacters

Richard Dipper, Qiong Guo

Let $U = U_{n} (q)$ be the group of lower unitriangular $n \times n$ -matrices with entries in the field $F_{q}$ with $q$ elements for some prime power $q$ and $n \in N$ . W…
