Brick Brauer–Thrall II' conjecture

Let Λ\Lambda be a finite-dimensional algebra. A module MmodΛM\in\operatorname{mod}\Lambda is a brick if EndΛ(M)\operatorname{End}_{\Lambda}(M) is a division algebra. The algebra Λ\Lambda is τ\tau-tilting infinite if it has infinitely many isomorphism classes of basic 22-term silting complexes. Brick Brauer–Thrall II' conjecture. If Λ\Lambda is τ\tau-tilting infinite, then there exists a dimension vector d\mathbf d such that there are infinitely many isomorphism classes of bricks MmodΛM\in\operatorname{mod}\Lambda of dimension vector d\mathbf d. This is also known as the τ\tau-Brauer–Thrall II' conjecture and is weaker than Pfeifer's stable version, which additionally requires a common stability parameter; its general status is not resolved in the supplied text.
