Double Hall algebras and derived equivalences

Quantum Algebra 2009-12-20 v5 Representation Theory

Abstract

We show that the reduced Drinfeld double of the Ringel-Hall algebra of a hereditary category is invariant under derived equivalences. By associating an explicit isomorphism to a given derived equivalence, we also extend the results of [BS1], [BS2], [SVdB], and [XY].
