The starting point is the derived McKay correspondence\, which establishes a derived equivalence between the mini mal resolution of an ADE singularity and a "noncommutative" surface encode d by the preprojective algebra of the corresponding affine ADE quiver.\n\n In the first part of the course\, we will give a brief introduction to Bri dgeland stability conditions on triangulated categories and study the spac es of stability conditions for the categories appearing in the derived McK ay correspondence. In the second part\, we will investigate the relationsh ips between cohomological Hall algebras (COHAs) arising from the triangula ted categories appearing in the derived McKay correspondence. Finally\, we will bring these two perspectives together and explain the construction o f a family of COHAs over the space of Bridgeland stability conditions.\n LOCATION:https://researchseminars.org/talk/HKUST-AG/99/ END:VEVENT END:VCALENDAR
