Symplectic Geometry SeminarThursday September 12th, 2019 Time: 11:00 AM Title: Relative Floer theoretic invariants Speaker: Umut Varolgunes, Stanford University Location: Math Tower 5-127 Abstract: I will start by explaining the construction of relative symplectic cohomology, in the c_1(M)=0 case for simplicity, as a graded algebra over the Novikov field. Then, I will list some of its properties including vanishing for stably displaceable subsets and a simple version of the Mayer-Vietoris property. I will also hopefully have some time to discuss the relative version of Lagrangian Floer homology in the tautologically unobstructed case. Part of this is my thesis, and part of it is joint work with D. Tonkonog.
