Superspace coinvariants and inverse systems for $G{L}_n({\mathbb{F}}_q)$

Brendon Rhoades, Andy Wilson

Let $q$ be a prime power and write $\Omega$ for the bigraded algebra of regular differential forms over ${\mathbb{F}}_q^n$. The general linear group $G{L}_n({\mathbb{F}}_q)$ acts on $\Omega$; writ…
