ON THE EXISTENCE OF MODULES WHICH ARE NEITHER PREPROJECTIVES NOR PREINJECTIVES

[摘要] Let A be a finite-dimensional algebra over an infinite perfect field. Suppose that each indecomposable A-module is either a preprojective or a preinjective in the sense defined by Auslander and Smalo. It is proved here that under these hypotheses A is of finite representation type. (C) 1994 Academic Press, Inc.
