Query: Improved exponential stability for near-integrable quasi-convex
  Hamiltonians   In this article, we improve previous results on exponential stability for
analytic and Gevrey perturbations of quasi-convex integrable Hamiltonian
systems. In particular, this provides a sharper upper bound on the speed of
Arnold diffusion which we believe to be optimal.
