The bounded-length brick conjecture for tau-tilting infinite algebras

Let Λ\Lambda be a finite-dimensional algebra, and let modΛ\operatorname{mod} \Lambda denote its category of finite-dimensional right Λ\Lambda-modules. A module is a brick if its endomorphism algebra is a division algebra, and its length is its composition length. Bounded-length brick conjecture. If Λ\Lambda is τ\tau-tilting infinite, then there exists a positive integer dd such that modΛ\operatorname{mod} \Lambda contains infinitely many pairwise non-isomorphic bricks of length dd. This conjecture seeks a uniform finite-length witness to τ\tau-tilting infiniteness; its status is not resolved by the supplied source context.
