Genus zero transverse foliations for weakly convex Reeb flows on the tight $3$ -sphere

Naiara V. de Paulo, Umberto Hryniewicz, Seongchan Kim +1

A contact form on the tight $3$ -sphere $(S^{3}, ξ_{0})$ is called weakly convex if the Conley-Zehnder index of every Reeb orbit is at least $2$ . In this article, we study Reeb flows of…

Generic properties of $3$ -dimensional Reeb flows: Birkhoff sections and entropy

Vincent Colin, Pierre Dehornoy, Umberto Hryniewicz +1

In this paper we use broken book decompositions to study Reeb flows on closed $3$ -manifolds. We show that if the Liouville measure of a nondegenerate contact form can be approximat…
