Mathematical Description of Chaos |
In General > s.a. chaos; classical
mechanics formalism [dynamical systems]; dimension.
* Statistical methods:
Usually statistical methods and entropy are considered applicable only to fully-chaotic
systems, but they may be applicable also at the edge of chaos by using Tsallis'
non-extensive generalizations.
@ Methods:
Sussman & Wisdom Sci(88)jul [power spectra];
Schack & Caves in(97)qp [sensitivity to perturbations];
Gilmore RMP(98) [topological, dissipative systems];
Korsch & Leyes NJP(02) [delocalization and measure on phase space];
Barrow & Levin n.CD/03 [test];
Gottwald & Melbourne PRS(04) [test];
Li & Zhang PLA(11) [for 2D Hamiltonian systems].
@ Curvature and geodesic deviation:
Szydłowski PLA(95) [N-body];
Di Bari & Cipriani PSS(98)cd/97;
Szczesny & Dobrowolski AP(99);
Wu JGP(09).
@ Statistical properties:
Ornstein & Weiss BAMS(91).
@ And entropy: Gu & Wang PLA(97);
Latora et al PLA(00)cm/99 [rate of increase];
Lissia et al cm/05-proc [Tsallis].

Cafaro PhD(08)-a1601.
Types of Chaos > s.a. Attractor [strange attractors];
fractals [Cantor set].
* Degree of chaoticity:
From weaker to stronger, ergodic – mixing – Kolmogorov.
* Origin of chaoticity:
Local sensitive dependence on initial conditions, together with global folding
of orbits; Can be continuously produced or in bursts (as in the billiard or
Bianchi IX models).
* Indicators: In low
dimensions, Poincaré sections are a good qualitative indicator;
In general, features of the power spectrum (~ square amplitude of Fourier
transform in time) of one dynamical variable or fractal basins of attraction
can be used, but Lyapunov exponents are quantitatively better.

Zaslavsky 04;
Calogero et al JPA(05) [transition to irregular motion in terms of Riemann surfaces];
Horwitz et al PRL(07)phy [in terms of curvature of metric].
@ Indicators: Lukes-Gerakopoulos et al PhyA(08) [and Tsallis entropy, Average Power Law Exponent].
Soft / Perturbative Chaos > s.a. KAM Theorem;
Mixing [including time scale]; Separatrix.
* Idea: When perturbing
an integrable system, if chaos sets in, it starts from local instabilities:
- The KAM theorem says that for small
perturbations most tori are undisturbed.
- The Melnikov method finds some
unstable places (homoclinic/heteroclinic orbits) where chaos might arise.
- The Lyapunv exponents say how
fast trajectories diverge locally.
- Arnold diffusion is the stronger
form of soft chaos.
* Stochastic web: A thread-like
region of chaotic dynamics in phase space generated by weak perturbations,
discovered by Arnold.
