Detecting the birth and death of finite-time coherent sets

  title={Detecting the birth and death of finite-time coherent sets},
  author={Gary Froyland and P{\'e}ter Koltai},
Finite-time coherent sets (FTCSs) are distinguished regions of phase space that resist mixing with the surrounding space for some finite period of time; physical manifestations include eddies and vortices in the ocean and atmosphere, respec-tively. The boundaries of finite-time coherent sets are examples of Lagrangian coherent structures (LCSs). The selection of the time duration over which FTCS and LCS computations are made in practice is crucial to their success. If this time is longer than the… 
A patch in time saves nine: Methods for the identification of localised dynamical behaviour and lifespans of coherent structures
We develop a transfer operator-based method for the detection of coherent structures and their associated lifespans. Characterising the lifespan of coherent structures allows us to identify
Persistence and material coherence of a mesoscale ocean eddy
Ocean eddies play an important role in the transport and mixing processes of the ocean due to their ability to transport material, heat, salt, and other tracers across large distances. They exhibit
Evolutionary clustering of Lagrangian trajectories in turbulent Rayleigh-Bénard convection flows.
We explore the transport mechanisms of heat in two- and three-dimensional turbulent convection flows by means of the long-term evolution of Lagrangian coherent sets. They are obtained from the

Almost-Invariant and Finite-Time Coherent Sets: Directionality, Duration, and Diffusion
Regions in the phase space of a dynamical system that resist mixing over a finite-time duration are known as almost-invariant sets (for autonomous dynamics) or coherent sets (for nonautonomous or
Robust FEM-Based Extraction of Finite-Time Coherent Sets Using Scattered, Sparse, and Incomplete Trajectories
Three FEM-based numerical methods are developed to efficiently approximate the dynamic Laplace operator, and a new dynamic isoperimetric problem using Dirichlet boundary conditions is introduced.
Lagrangian based methods for coherent structure detection.
A review of four Lagrangian analytical methods for detecting coherent structures in fluid flow transport via their application to the same sample analytic model, the canonical double-gyre flow, highlighting the pros and cons of each approach.
A tale of two vortices: How numerical ergodic theory and transfer operators reveal fundamental changes to coherent structures in non-autonomous dynamical systems
This work develops and implements algorithms providing multilayered descriptions of time-dependent systems which are not only useful for locating coherent structures, but also for detecting time windows within which these structures undergo fundamental structural changes, such as merging and splitting events.
Dynamic isoperimetry and the geometry of Lagrangian coherent structures
The study of transport and mixing processes in dynamical systems is particularly important for the analysis of mathematical models of physical systems. We propose a novel, direct geometric method to
Estimating long-term behavior of periodically driven flows without trajectory integration
Periodically driven flows are fundamental models of chaotic behavior and the study of their transport properties is an active area of research. A well-known analytic construction is the augmentation
Linear response for the dynamic Laplacian and finite-time coherent sets
Finite-time coherent sets represent minimally mixing objects in general nonlinear dynamics, and are spatially mobile features that are the most predictable in the medium term. When the dynamical
Computation and Optimal Perturbation of Finite-Time Coherent Sets for Aperiodic Flows Without Trajectory Integration
This work considers the relevant transfer operators and their infinitesimal generators on an augmented space-time manifold to compute coherent sets from an aperiodic time-dependent dynamical system and obtains explicit solutions for these optimization problems using Lagrange multipliers.
