The Lorenz system as a gradient-like system

Jeremy P Parker

We formulate, for continuous-time dynamical systems, a sufficient condition to be a gradient-like system, i.e. that all bounded trajectories approach stationary points and therefor…

Predicting chaotic statistics with unstable invariant tori

Jeremy P. Parker, Omid Ashtari, Tobias M. Schneider

It has recently been speculated that statistical properties of chaos may be captured by weighted sums over unstable invariant tori embedded in the chaotic attractor of hyperchaotic…

Koopman analysis of the periodic Korteweg-de Vries equation

Jeremy P Parker, Claire Valva

The eigenspectrum of the Koopman operator enables the decomposition of nonlinear dynamics into a sum of nonlinear functions of the state space with purely exponential and sinusoida…

Invariant tori in dissipative hyperchaos

Jeremy P Parker, Tobias M Schneider

One approach to understand the chaotic dynamics of nonlinear dissipative systems is the study of non-chaotic yet dynamically unstable invariant solutions embedded in the system's c…

A study of the double pendulum using polynomial optimization

Jeremy P Parker, David Goluskin, Geoffrey M Vasil

In dynamical systems governed by differential equations, a guarantee that trajectories emanating from a given set of initial conditions do not enter another given set can be obtain…

The viscous Holmboe instability for smooth shear and density profiles

Jeremy P. Parker, Colm-cille P. Caulfield, Rich R. Kerswell

The Holmboe wave instability is one of the classic examples of a stratified shear instability, usually explained as the result of a resonance between a gravity wave and a vorticity…

Kelvin-Helmholtz billows above Richardson number

J. P. Parker, C. P. Caulfield, R. R. Kerswell

We study the dynamical system of a forced stratified mixing layer at finite Reynolds number , and Prandtl number . We consider a hyperbolic tangent background velocity pr…

Koopman analysis of isolated fronts and solitons

Jeremy Parker, Jacob Page

A Koopman decomposition of a complex system leads to a representation in which nonlinear dynamics appear to be linear. The existence of a linear framework with which to analyse non…
