Query: Stability conditions and Kleinian singularities   We describe the spaces of stability conditions on certain triangulated
categories associated to Dynkin diagrams. These categories can be defined
either algebraically via module categories of preprojective algebras, or
geometrically via coherent sheaves on resolutions of Kleinian singularities.
The resulting spaces are related to regular subsets of the corresponding
complexified Cartan algebras.
