Finsler geodesics, periodic Reeb orbits, and open books
Max Dörner, Hansjörg Geiges, Kai Zehmisch
We survey some results on the existence (and non-existence) of periodic Reeb orbits on contact manifolds, both in the open and closed case. We place these statements in the context…

Two constructions of virtually contact structures
Kevin Wiegand, Kai Zehmisch
Motivated by recent developments in proving the Weinstein conjecture we introduce the notion of covering contact connected sum for virtually contact manifolds and construct virtual…

The diffeomorphism type of symplectic fillings
Kilian Barth, Hansjörg Geiges, Kai Zehmisch
We show that simply connected contact manifolds that are subcritically Stein fillable have a unique symplectically aspherical filling up to diffeomorphism. Various extensions to ma…
