The Hall algebra of a cyclic quiver at $q=0$

Stefan Wolf

Published 2007-09-27Version 1

We show that the generic Hall algebra of nilpotent representations of an oriented cycle specialised at $q=0$ is isomorphic to the generic extension monoid in the sense of Reineke. This continues the work of Reineke.
