Left-handed geodesic flow of spheres of revolution

Pierre Dehornoy, Ana Rechtman

A flow on a 3-manifold is left-handed if any two ergodic invariant measures have negative linking number. We prove that on a 2-sphere of revolution whose curvature is -pinched…

Homoclinic orbits, Reeb chords and nice Birkhoff sections for Reeb flows in 3D

Vincent Colin, Umberto Hryniewicz, Ana Rechtman

We prove that for a -generic contact form defining a given co-oriented contact structure on a closed -manifold, every hyperbolic periodic Reeb orbit admits a transvers…

Properties of contact toric structures and concave boundaries of linear plumbings

Aleksandra Marinković, Jo Nelson, Ana Rechtman +3

We consider plumbings of symplectic disk bundles over spheres admitting concave contact boundary, with the goal of understanding the geometric properties of the boundary contact st…

Periodic orbits and Birkhoff sections of stable Hamiltonian structures

Robert Cardona, Ana Rechtman

Stable Hamiltonian structures generalize contact forms and define a volume-preserving vector field known as the Reeb vector field. We study two aspects of Reeb vector fields define…

Generic properties of -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 -manifolds. We show that if the Liouville measure of a nondegenerate contact form can be approximat…

Kuperberg Dreams

Steven Hurder, Ana Rechtman

The ``Seifert Conjecture'' stated, ``Every non-singular vector field on the 3-sphere has a periodic orbit''. In a celebrated work, Krystyna Kuperberg gave a constru…
