Cluster exchange groupoids and framed quadratic differentials

Speaker: Dr. Yu Qiu (The Chinese University of Hong Kong)

(II). Cluster exchange groupoids and framed quadratic differentials

Abstract:   We introduce cluster exchange groupoids, whose points groups give the  generalized braid groups--the cluster braid groups. As application, we  construct spaces of framed quadratic differentials on decorated marked  surfaces, that realized spaces of stability conditions, and show that  these spaces are simply connected. (Joint with Alastair King)
