Robust FEM-based extraction of finite-time coherent sets using scattered, sparse, and incomplete trajectories
Gary Froyland, Oliver Junge
Transport and mixing properties of aperiodic flows are crucial to a dynamical analysis of the flow, and often have to be carried out with limited information. Finite-time coherent…
A spectral approach for quenched limit theorems for random expanding dynamical systems
Davor Dragicevic, Gary Froyland, Cecilia Gonzalez-Tokman +1
We prove quenched versions of (i) a large deviations principle (LDP), (ii) a central limit theorem (CLT), and (iii) a local central limit theorem (LCLT) for non-autonomous dynamica…
A Critical Comparison of Lagrangian Methods for Coherent Structure Detection
Alireza Hadjighasem, Mohammad Farazmand, Daniel Blazevski +2
We review and test twelve different approaches to the detection of finite-time coherent material structures in two-dimensional, temporally aperiodic flows. We consider both mathema…
Hilbert Space Lyapunov Exponent stability
Gary Froyland, Cecilia González-Tokman, Anthony Quas
We study cocycles of compact operators acting on a separable Hilbert space, and investigate the stability of the Lyapunov exponents and Oseledets spaces when the operators are subj…
Lagrangian dynamical geography of the Gulf of Mexico
P. Miron, F. J. Beron-Vera, M. J. Olascoaga +3
We construct a Markov-chain representation of the surface-ocean Lagrangian dynamics in a region occupied by the Gulf of Mexico (GoM) and adjacent portions of the Caribbean Sea and…
