Topology Seminar——Braid groups via cluster exchange groupoids
报告人：Yu Qiu (Tsinghua University)

Abstract: We construct braid groups from cluster exchange groupoids with application to the study of moduli spaces of meromorphic quadratic differentials on Riemann surfaces and space of stability conditions on the associated Calabi-Yau-3 categories. This is a joint work with Alastair King.
