摘要:As a generalization of (generalized) braid group of quivers, we introduce braid groups associated to quivers with potential (arising from surfaces). We showed that these groups act faithfully on certain 3-Calabi-Yau categories. We also give finite presentations of these groups via braid twists of decorated surfaces. This talk is based on joint work with Yu Qiu.
