Contact Dehn surgery, symplectic fillings, and Property P for knots
Hansjörg Geiges
These are notes of a talk given at the Mathematische Arbeitstagung 2005 in Bonn. Following ideas of Ozbagci-Stipsicz, a proof based on contact Dehn surgery is given of Eliashberg's…
-plumbings and exotic contact structures on spheres
Fan Ding, Hansjörg Geiges
We prove the existence of exotic but homotopically trivial contact structures on spheres of dimension 8k-1. Together with previous results of Eliashberg and the second author this…
Lutz twist and contact surgery
Fan Ding, Hansjörg Geiges, András I. Stipsicz
For any knot T transverse to a given contact structure on a 3-manifold, we exhibit a Legendrian two-component link such that T equals the transverse push-off of one of the link com…
Surgery diagrams for contact 3-manifolds
Fan Ding, Hansjörg Geiges, András I. Stipsicz
In two previous papers, the two first-named authors introduced a notion of contact r-surgery along Legendrian knots in contact 3-manifolds. They also showed how (at least in princi…
On the topology of the space of contact structures on torus bundles
Hansjörg Geiges, Jesús Gonzalo
We prove the existence of essential loops in the space of contact structures on torus bundles over the circle.
Moduli of contact circles
Hansjörg Geiges, Jesús Gonzalo
We continue the study of linear families of contact forms on 3-manifolds begun in our paper `Contact geometry and complex surfaces'. The present paper introduces Teichmuller and mo…
