On the cohomology ring of symplectic fillings
arXiv:1902.06360 · doi:10.2140/agt.2023.23.1693
Abstract
We consider symplectic cohomology twisted by sphere bundles, which can be viewed as an analogue of local systems. Using the associated Gysin exact sequence, we prove the uniqueness of part of the ring structure on cohomology of fillings for those asymptotically dynamically convex manifolds with vanishing property considered in [30,31]. In particular, for simply connected dimensional flexible fillable contact , we show that real cohomology is unique as a ring for any Liouville filling of as long as . Uniqueness of real homotopy type of Liouville fillings is also obtained for a class of flexibly fillable contact manifolds.
