The $\ell$-modular representation of reductive groups over finite local rings of length two

Nariel Monteiro

Let ${\mathcal{O}}_2$ and ${\mathcal{O}}_2^{\prime }$ be two distinct finite local rings of length two with residue field of characteristic $p$. Let $\mathbb{G}({\mathcal{O}}_2)$ and $\mathbb{G}(…
