A variational theory of hyperbolic Lagrangian coherent structures (vol 240, pg 574, 2011)

This brief note corrects a minor error in the statement of the main result in Haller (2011) [1] on a variational approach to Lagrangian coherent structures. We also show that the corrected formulation leads to a substantial simplification of LCS criteria for two-dimensional flows. (C) 2011 Elsevier B.V. All rights reserved.
