Decomposition numbers for the principal $Φ_{2 n}$ -block of $Sp_{4 n} (q)$ and $SO_{4 n + 1} (q)$

Olivier Dudas, Emily Norton

We compute the decomposition numbers of the unipotent characters lying in the principal $ℓ$ -block of a finite group of Lie type $B_{2 n} (q)$ or $C_{2 n} (q)$ when $q$ is an odd pri…

We compute the Ext-algebra of the Brauer tree algebra associated to a line with no exceptional vertex.
