On the cardinality of measures of maximal relative entropy for smooth skew products
Matheus M. Castro, Gary Froyland
Let and be compact smooth manifolds and let be a skew-product diffeomorphism over a transitive Anosov base. We show that ha…
Transient almost-invariant sets reveal convective heat transfer patterns in plane-layer Rayleigh-Bénard convection
Aleksandar Badza, Gary Froyland, Roshan J. Samuel +1
Horizontally extended plane-layer convection flows are characterized by characteristic patterns of turbulent heat transfer due to the convective fluid motion consisting of a nearly…
Learning dynamically inspired bases for Koopman and transfer operator approximation
Gary Froyland, Kevin Kühl
Transfer and Koopman operator methods offer a framework for representing complex, nonlinear dynamical systems via linear transformations, enabling a deeper understanding of the und…
Multi-set spectral clustering of time-evolving networks using the supra-Laplacian
Gary Froyland, Manu Kalia, Péter Koltai
Complex time-varying networks are prominent models for a wide variety of spatiotemporal phenomena. The functioning of networks depends crucially on their connectivity, yet reliable…
