Proof of Hofer-Wysocki-Zehnder's two or infinity conjecture

Dan Cristofaro-Gardiner, Umberto Hryniewicz, Michael Hutchings +1

We prove that every Reeb flow on a closed connected three-manifold has either two or infinitely many simple periodic orbits, assuming that the associated contact structure has tors…

Non-hyperbolic closed characteristics on non-degenerate star-shaped hypersurfaces in $R^{2 n}$

Huagui Duan, Hui Liu, Yiming Long +1

In this paper, we prove that for every index perfect non-degenerate compact star-shaped hypersurface $Σ \subset R^{2 n}$ , there exist at least $n$ non-hyperbolic closed characte…
