Abstract: In my thesis, I introduced a Floer theoretic invariant for compact subsets of symplectic manifolds called relative symplectic cohomology. This invariant has already proved to be very useful in symplectic rigidity questions and also opened the way to a fruitful reinterpretation of mirror symmetry. Most of these applications rely on an analogue of Mayer-Vietoris property from topology that holds for relative symplectic cohomology under well-understood geometric assumptions. I will briefly introduce the invariant, discuss the Mayer-Vietoris property and present some computations relevant to mirror symmetry. No background in symplectic geometry will be assumed.
