Some remarks on the geometry of the Standard Map
arXiv:0810.3122 · doi:10.1142/S0218127409024025
Abstract
We define and compute hyperbolic coordinates and associated foliations which provide a new way to describe the geometry of the standard map. We also identify a uniformly hyperbolic region and a complementary 'critical' region containing a smooth curve of tangencies between certain canonical 'stable' foliations.
