Which Canonical Algebras are Derived Equivalent to Incidence Algebras of Posets?

Pages 4599-4606 | Received 30 Aug 2007, Published online: 12 Dec 2008
 

Abstract

We give a full description of all the canonical algebras over an algebraically closed field that are derived equivalent to incidence algebras of finite posets. These are the canonical algebras whose number of weights is either 2 or 3.
