Contact spheres and hyperkähler geometry
Hansjörg Geiges, Jesús Gonzalo
A taut contact sphere on a 3-manifold is a linear 2-sphere of contact forms, all defining the same volume form. In the present paper we completely determine the moduli of taut cont…
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…
A Legendrian surgery presentation of contact 3-manifolds
Fan Ding, Hansjörg Geiges
We prove that every closed, connected contact 3-manifold can be obtained from the 3-sphere with its standard contact structure by contact surgery of coefficient plus or minus 1 alo…
Symplectic fillability of tight contact structures on torus bundles
Fan Ding, Hansjorg Geiges
We study weak versus strong symplectic fillability of some tight contact structures on torus bundles over the circle. In particular, we prove that almost all of these tight contact…
