Flat metrics are strict local minimizers for the polynomial entropy

Flat metrics are strict local minimizers for the polynomial entropy As we have proved in [11], the geodesic flows associated with the flat metrics on $$ \mathbb{T}^2 $$ minimize the polynomial entropy hpol. In this paper, we show that, among the geodesic flows that are Bott integrable and dynamically coherent, the geodesic flows associated with flat metrics are local strict minima for hpol. To this aim, we prove a graph property for invariant Lagrangian tori in near-integrable systems. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Regular and Chaotic Dynamics Springer Journals

Abstract

As we have proved in [11], the geodesic flows associated with the flat metrics on $$ \mathbb{T}^2 $$ minimize the polynomial entropy hpol. In this paper, we show that, among the geodesic flows that are Bott integrable and dynamically coherent, the geodesic flows associated with flat metrics are local strict minima for hpol. To this aim, we prove a graph property for invariant Lagrangian tori in near-integrable systems.
