[图书][B] Lyapunov exponents: a tool to explore complex dynamics

A Pikovsky, A Politi - 2016 - books.google.com
Lyapunov exponents lie at the heart of chaos theory, and are widely used in studies of
complex dynamics. Utilising a pragmatic, physical approach, this self-contained book …

Predictability of large-scale atmospheric motions: Lyapunov exponents and error dynamics

S Vannitsem - Chaos: An Interdisciplinary Journal of Nonlinear …, 2017 - pubs.aip.org
The deterministic equations describing the dynamics of the atmosphere (and of the climate
system) are known to display the property of sensitivity to initial conditions. In the ergodic …

Dispersion of passive tracers in closed basins: Beyond the diffusion coefficient

V Artale, G Boffetta, A Celani, M Cencini, A Vulpiani - Physics of Fluids, 1997 - pubs.aip.org
We investigate the spreading of passive tracers in closed basins. If the characteristic length
scale of the Eulerian velocities is not very small compared with the size of the basin the …

Collective chaos in pulse-coupled neural networks

S Olmi, A Politi, A Torcini - Europhysics Letters, 2011 - iopscience.iop.org
We study the dynamics of two symmetrically coupled populations of identical leaky integrate-
and-fire neurons characterized by an excitatory coupling. Upon varying the coupling …

Chaos or noise: Difficulties of a distinction

M Cencini, M Falcioni, E Olbrich, H Kantz, A Vulpiani - Physical Review E, 2000 - APS
In experiments, the dynamical behavior of systems is reflected in time series. Due to the
finiteness of the observational data set, it is not possible to reconstruct the invariant measure …
