B3: Systolic inequalities in Reeb dynamics
Abbondandolo, Bramham, Hryniewicz
The aim of this project is to extend some notions from classical systolic geometry to Reeb dynamics. In particular, we would like to carry out a thorough study of the ratio of the n-th power of the minimal action of a closed characteristic by the contact volume. Typical questions which we would like to address are, Is this ratio bounded from above on meaningful classes of contact forms? Is the maximum achieved? Although not a symplectically invariant notion, convexity seems to play a special role, why? Answers to these questions are expected to shed some light on important open problems in symplectic topology, Riemannian and Finsler systolic geometry, convex analysis and billiard dynamics.
