The second brick-Brauer-Thrall conjecture
The second brick-Brauer-Thrall conjecture
Let be a finite-dimensional algebra over a field . Write for the set of isomorphism classes of bricks of dimension , and call brick-finite if it has only finitely many bricks up to isomorphism. Second brick-Brauer-Thrall conjecture. The algebra is brick-finite if and only if is a finite set for every . This conjecture connects brick-finiteness with the bounded-dimension behavior of bricks; it was settled for special biserial algebras and other families, but the source records it as having been resolved in that setting.
