Bridgeland stability conditions on the acyclic triangular quiver

Abstract

Using results in a previous paper "Non-semistable exceptional objects in hereditary categories", we focus here on studying the topology of the space of Bridgeland stability conditions on $D^b(Re{p}_k(Q))$, where $Q$ is the acyclic triangular quiver (the underlying graph is the extended Dynkin diagram ${\tilde{\mathbb{A}}}_2$). In particular, we prove that this space is contractible (in the previous paper it was shown that it is connected).
