DESCRIPTION:Title: <a href="https://researchseminars.org/talk/iccm2020/7/"
 >Cluster exchange groupoids and framed quadratic differentials</a>\nby Qiu
  Yu/邱宇 (Tsinghua University) as part of ICCM 2020\n\n\nAbstract\nWe in
 troduce the cluster exchange groupoids to show that any connected componen
 t (which are all isomorphic) of the moduli space of framed quadratic diffe
 rentials on a decorated marked surface S_Delta is simply connected. We als
 o improve the result of Bridgeland-Smith\, that such a space can be identi
 fied with the principal component of the space of stability conditions on 
 the associated Calabi-Yau-3 categories of S_Delta. If time permits\, we wi
 ll discuss q-deformations on Calabi-Ya categories\, stability conditions a
 nd quadratic differentials.\n
