The Lyapunov exponent characterizes an exponential growth rate of the difference of nearby orbits. A positive Lyapunov exponent (exponential dynamical instability) is a manifestation of chaos. Here, we propose the Lyapunov pair, which is based on the generalized Lyapunov exponent, as a unified characterization of nonexponential and exponential dynamical instabilities in one-dimensional maps. Chaos is classified into three different types, i.e., superexponential, exponential, and subexponential…

Lyapunov Exponents and the Belousov-Zhabotinsky Oscillator: An Interactive Computational Approach
The Belousov-Zhabotinsky (BZ) chemical oscillator is the most studied oscillator. It has been modelled on the basis of single-step mechanisms which have been continuously refined since the seminal
Exact Lyapunov exponents of the generalized Boole transformations
The generalized Boole transformations have rich behavior ranging from the \textit{mixing} phase with the Cauchy invariant measure to the \textit{dissipative} phase through the \textit{infinite
A Simple Nonlinear Circuit Contains an Infinite Number of Functions
TLDR
This brief shows that the number of different functions that a nonlinear or chaotic circuit can implement exponentially increases as the circuit evolves in time, and this exponential increase is quantified with an exponent that is named the computing exponent.
Estimating ergodization time of a chaotic many-particle system from a time reversal of equilibrium noise
We propose a method of estimating ergodization time of a chaotic many-particle system by monitoring equilibrium noise before and after time reversal of dynamics (Loschmidt echo). The ergodization

TLDR
Based on a certain transport coefficient obtained from a single trajectory, a relation is provided for the transport coefficients divided by the Lyapunov exponent and generalize the Einstein relation for single trajectories.
Subexponential instability in one-dimensional maps implies infinite invariant measure.
TLDR
It is shown that a one-dimensional, conservative, ergodic measure preserving map with subexponential instability has an infinite invariant measure, and then a generalized Lyapunov exponent is presented to characterize subexp exponential instability.

The most striking result is that the maximum diversity appears at the transition point from stationary chaos to non-stationary chaos where the exact 1/f spectral process is generated.
