Systems of global surfaces of section for dynamically convex Reeb flows on the 3-sphere

Umberto Hryniewicz

We characterize which closed Reeb orbits of a dynamically convex contact form on the 3-sphere bound disk-like global surfaces of section for the Reeb flow, without any genericity a…

Global properties of tight Reeb flows with applications to Finsler geodesic flows on $S^{2}$

Umberto Hryniewicz, Pedro A. S. Salomão

We show that if a Finsler metric on $S^{2}$ with reversibility $r$ has flag curvatures $K$ satisfying $(\frac{r}{r + 1})^{2} < K \leq 1$ , then closed geodesics with specific contact-topol…
