A $9$-dimensional algebra which is not a block of a finite group

Markus Linckelmann, William Murphy

Published 2020-05-05Version 1

We rule out a certain $9$-dimensional algebra over an algebraically closed field to be the basic algebra of a block of a finite group, thereby completing the classification of basic algebras of dimension at most $12$ of blocks of finite group algebras.
