Abstract / Bemerkung
We consider representations of a quiver over an arbitrary field. Recall that an indecomposable representation M without self-extensions is said to be exceptional. We are going to show that exceptional representations can be exhibited using matrices involving as coefficients just 0 and 1. Actually, if d is the dimension of M, there exists such a matrix presentation with precisely d-1 non-zero coefficients: the corresponding "coeffcient quiver" is a tree. (C) 1998 Elsevier Science Inc.
