Chern-Weil theory and the group of strict contactomorphisms
Roger Casals, Oldřich Spáčil
In this paper we study the groups of contactomorphisms of a closed contact manifold from a topological viewpoint. First we construct examples of contact forms on spheres whose Reeb…

Roger Casals, Francisco Presas, Sheila Sandon
We prove that on overtwisted contact manifolds there can be no positive loops of contactomorphisms that are generated by a -small Hamiltonian function.
