-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…
The Chen-Ruan Cohomology of Almost Contact Orbifolds
Fan Ding, Yunfeng Jiang, Jianzhong Pan
Comparing to the Chen-Ruan cohomology theory for the almost complex orbifolds, we study the orbifold cohomology theory for almost contact orbifolds. We define the Chen-Ruan cohomol…
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…
