Persistence and material coherence of a mesoscale ocean eddy
Michael C. Denes, Gary Froyland, Shane R. Keating
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 distan…
Deep Lagrangian connectivity in the global ocean inferred from Argo floats
Ryan Abernathey, Christopher Bladwell, Gary Froyland +1
We describe the application of a new technique from nonlinear dynamical systems to infer the Lagrangian connectivity of the deep global ocean. We approximate the dynamic Laplacian…
Equilibrium states for non-transitive random open and closed dynamical systems
Jason Atnip, Gary Froyland, Cecilia González-Tokman +1
We prove a random Ruelle--Perron--Frobenius theorem and the existence of relative equilibrium states for a class of random open and closed interval maps, without imposing transitiv…
Spectral analysis of climate dynamics with operator-theoretic approaches
Gary Froyland, Dimitrios Giannakis, Benjamin Lintner +2
The Earth's climate system is a classical example of a multiscale, multiphysics dynamical system with an extremely large number of active degrees of freedom, exhibiting variability…
Thermodynamic Formalism for Random Interval Maps with Holes
Jason Atnip, Gary Froyland, Cecilia González-Tokman +1
We develop a quenched thermodynamic formalism for open random dynamical systems generated by finitely branched, piecewise-monotone mappings of the interval. The openness refers to…
Detecting the birth and death of finite-time coherent sets
Gary Froyland, Péter 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 inc…
Optimal linear response for Markov Hilbert-Schmidt integral operators and stochastic dynamical systems
Fadi Antown, Gary Froyland, Stefano Galatolo
We consider optimal control problems for discrete-time random dynamical systems, finding unique perturbations that provoke maximal responses of statistical properties of the system…
