Smooth perfectness through decomposition of diffeomorphisms into fiber preserving ones

Stefan Haller, Josef Teichmann

We show that on a closed smooth manifold $M$ equipped with $k$ fiber bundle structures whose vertical distributions span the tangent bundle, every smooth diffeomorphism $f$ of $M$ …

Non-contractible periodic trajectories of symplectic vector fields, Floer cohomology and symplectic torsion

Dan Burghelea, Stefan Haller

For a closed symplectic manifold $(M, ω)$ , a compatible almost complex structure $J$ , a 1-periodic time dependent symplectic vector field $Z$ and a homotopy class of closed curves $…

On the topology and analysis of a closed one form. I (Novikov's theory revisited)

Dan Burghelea, Stefan Haller

We consider systems $(M, ω, g)$ with $M$ a closed smooth manifold, $ω$ a real valued closed one form and $g$ a Riemannian metric, so that $(ω, g)$ is a Morse-Smale pair, Definition~2.…
