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…

The McKay correspondence for isolated singularities via Floer theory
Mark McLean, Alexander F. Ritter
We prove the generalised McKay correspondence for isolated singularities using Floer theory. Given an isolated singularity \C^n/G for a finite subgroup G in SL(n,\C) and any crepan…
