Identifying dynamical boundaries and phase space transport using Lagrangian coherent structures
P Tallapragada - 2010 - vtechworks.lib.vt.edu
In many problems in dynamical systems one is interested in the identification of sets which
have qualitatively different fates. The finite-time Lyapunov exponent (FTLE) method is a …
