Quantum cohomology and Floer invariants of semiprojective toric manifolds
Alexander F. Ritter, Filip Živanović
We use Floer theory to describe invariants of symplectic -manifolds admitting several commuting -actions. The -actions induce filtrations…

Filtrations on equivariant quantum cohomology and Hilbert-Poincaré series
Alexander F. Ritter, Filip Živanović
We prove that Floer theory induces a filtration by ideals on equivariant quantum cohomology of symplectic manifolds equipped with a -action. In particular, this gives…

Invariance of symplectic cohomology and twisted cotangent bundles over surfaces
Gabriele Benedetti, Alexander F. Ritter
We prove that symplectic cohomology for open convex symplectic manifolds is invariant when the symplectic form undergoes deformations which may be non-exact and non-compactly suppo…
