Cluster exchange groupoids and decorated marked
I will explain how to turn the cluster exchange graph of
triangulations of a marked surface into a groupoid in such way that the
universal cover can be constructed using `decorated' triangulations. As an
application, the space of Bridgeland stability conditions for the associated
Ginzburg algebra is simply connected.
