Enomoto's semibrick finiteness conjecture for finite-dimensional algebras
Enomoto's semibrick finiteness conjecture for finite-dimensional algebras
Let be a finite-dimensional algebra. A semibrick in is a set of bricks whose distinct members have no nonzero morphisms between them. Enomoto's conjecture. If every semibrick in is a finite set, then is brick-finite, that is, is -tilting finite.
This conjecture asks whether finiteness of every semibrick forces finiteness of the set of bricks. Enomoto established several equivalent characterizations of brick-finite algebras, while the stated implication remains the conjectural direction.
