The DO and Schur-representation finiteness conjectures for algebras

Let Λ\Lambda be an algebra. The properties of being DO, Schur-representation-finite, and τ\tau-tilting finite are considered.

DO and Schur-representation finiteness conjectures. The following hold:

  1. If Λ\Lambda is DO, then it is τ\tau-tilting finite.
  2. Λ\Lambda is Schur-representation-finite if and only if Λ\Lambda is τ\tau-tilting finite.

These implications are established for minimal representation-infinite non-distributive and biserial algebras, and for further specified families, but remain conjectural in general.
