Symplectic circle actions on manifolds with contact type boundary
Aleksandra Marinković, Klaus Niederkrüger-Eid
Many of the existing results for closed Hamiltonian G-manifolds are based on the analysis of the corresponding Hamiltonian functions using Morse-Bott techniques. In general such me…
On the symplectic fillings of standard real projective spaces
Paolo Ghiggini, Klaus Niederkrüger-Eid
We prove, in a geometric way, that the standard contact structure on the real projective space of dimension is not Liouville fillable for and odd. We also prove th…
On properties of Bourgeois contact structures
Samuel Lisi, Aleksandra Marinković, Klaus Niederkrüger
The Bourgeois construction associates to every contact open book on a manifold a contact structure on . We study in this article some of the properties of that…
Examples of non-trivial contact mapping classes in all dimensions
Patrick Massot, Klaus Niederkrüger
We give examples of contactomorphisms in every dimension that are smoothly isotopic to the identity but that are not contact isotopic to the identity. In fact, we prove the stronge…
Loose Legendrians and the plastikstufe
Emmy Murphy, Klaus Niederkrüger, Olga Plamenevskaya +1
We show that the presence of a plastikstufe induces a certain degree of flexibility in contact manifolds of dimension 2n+1>3. More precisely, we prove that every Legendrian knot wh…
Weak and strong fillability of higher dimensional contact manifolds
Patrick Massot, Klaus Niederkrüger, Chris Wendl
For contact manifolds in dimension three, the notions of weak and strong symplectic fillability and tightness are all known to be inequivalent. We extend these facts to higher dime…
