A new concept of local metric entropy for finite-time nonautonomous dynamical systems

Dynamical Systems 2014-06-27 v3

Abstract

We introduce a new concept of finite-time entropy which is a local version of the classical concept of metric entropy. Based on that, a finite-time version of Pesin's entropy formula and also an explicit formula of finite-time entropy for 22-D systems are derived. We also discuss about how to apply the finite-time entropy field to detect special dynamical structures such as Lagrangian coherent structures.
