KAM splittings and equidistributed periodic orbits for stable hypersurfaces

Robert Cardona, Oliver Edtmair, Rohil Prasad

We show that any stable hypersurface of a symplectic -manifold, on which the cohomology class of the symplectic form restricts to a multiple of a rational class, can be $C^\inft…

Smooth perfectness of Hamiltonian diffeomorphism groups

Oliver Edtmair

A fundamental result of Banyaga states that the Hamiltonian diffeomorphism group of a closed symplectic manifold is perfect. We refine this result by proving that, locally in the $…

Packing stability and the subleading asymptotics of symplectic Weyl laws

Oliver Edtmair

We prove that symplectic ball packing stability holds for every compact, connected symplectic -manifold with smooth boundary. This follows from a stronger result: the full volum…

A universal extension of helicity to topological flows

Oliver Edtmair, Sobhan Seyfaddini

Helicity is a fundamental conserved quantity in physical systems governed by vector fields whose evolution is described by volume-preserving transformations on a three-manifold. No…

An elementary alternative to PFH spectral invariants

Oliver Edtmair

Inspired by Hutchings' elementary alternative to ECH capacities, we introduce an elementary alternative to spectral invariants defined via periodic Floer homology (PFH). We use the…

PFH spectral invariants and closing lemmas

Oliver Edtmair, Michael Hutchings

We develop the theory of spectral invariants in periodic Floer homology (PFH) of area-preserving surface diffeomorphisms. We use this theory to prove closing lemmas for…
