The computation of finite-time Lyapunov exponents on unstructured meshes and for non-Euclidean manifolds
(American Institute of Physics, 2010-03-01)
We generalize the concepts of finite-time Lyapunov exponent (FTLE) and Lagrangian coherent structures to arbitrary Riemannian manifolds. The methods are illustrated for convection cells on cylinders and Moumlbius strips, ...
