Some formulae relating modular representations of elementary abelian $p$ -groups

Jonathan Elmer, Kazal Kadr

Let $p > 0$ be a prime, $k$ a field of characteristic $p$ and $G$ and elementary abelian $p$ -group of order $q = p^{n}$ . Let $W$ be an indecomposable $k G$ -module of dimension 2 and def…

The separating variety for matrix invariants

Jonathan Elmer

Let $G$ be a linear algebraic group defined over an algebraically closed field $k$ , and let $V$ be a vector space on which $G$ acts linearly. The separating variety $\mathcal{S}_{G…
