Action minimizing properties and distances on the group of Hamiltonian diffeomorphisms

Alfonso Sorrentino and Claude Viterbo

Geometry & Topology 14 (2010) 2383–2403
Abstract

In this article we prove that for a smooth fiberwise convex Hamiltonian, the asymptotic Hofer distance from the identity gives a strict upper bound to the value at 0 of Mather’s β function, thus providing a negative answer to a question asked by Siburg [Duke Math. J. 92 (1998) 295-319]. However, we show that equality holds if one considers the asymptotic distance defined in Viterbo [Math. Ann. 292 (1992) 685-710].
