Topological type Fukaya categories and Calabi-Yau/Cluster categories

A Series of Talks in Cluster Theory Speaker: Dr. Yu Qiu (The Chinese University of Hong Kong) (I). Topological type Fukaya categories and Calabi-Yau/Cluster categories. Abstract: We introduce Calabi-Yau-X categories of quivers with superpotential from surfaces and show that their cluster categories are topological Fukaya categories. We also survey various topological type Fukaya...
