Abstract

We introduce the notion of n-representation-finiteness, generalizing
representation-finite hereditary algebras. We establish the procedure of n-APR
tilting, and show that it preserves n-representation-finiteness. We give some
combinatorial description of this procedure, and use this to completely
describe a class of n-representation-finite algebras called ``type A''.
