摘要:Let A=kQ/I be a gentle algebra. It is well-known that A is representation-infinite if and only if its bound quiver (Q, I) contains a band. In this talk, we provide a new description of the representation-types of gentle algebras by using marked surfaces, and show that A is representation-infinite if and only if there exists a Gorenstein-projective support tau-tilting module T such that EndT is representation-infinite.
