YMSC Topology Seminar

Simplicial arrangements and the geometry of planar cubic curves Guillaume TAHAR, BIMSA (2024-10-17) Abstract: In their solution to the orchard-planting problem, Green and Tao established a structure theorem which proves that in a line arrangement in the real projective plane with few double points, most lines are tangent to the dual curve of a cubic curve. We provide geometric arguments to prov...

Tsinghua-BIMSA symplectic geometry seminar

Schedule:Oct 9 Kenji Fukaya (Tsinghua)Categorification of Atiyah-Floer conjecture Abstract: Atiyah-Floer conjecture relates two versions of Floer homologies one in gauge theory the other in symplectic geometry. I will explain how we “upgrade”it to a functorial equivalence of 2-A-infinity categories. Also I will explain its 2-3 dimensional topological Field theory and Lagrangian correspondence...
