We consider a general class of intermittent maps designed to be weakly chaotic, i.e., for which the separation of trajectories of nearby initial conditions is weaker than exponential. We show that all its spatio and temporal properties, hitherto regarded independently in the literature, can be represented by a single characteristic function ϕ. A universal criterion for the choice of ϕ is obtained within the Feigenbaum’s renormalization-group approach. We find a general expression for the… Expand

Number of first-passage times as a measurement of information for weakly chaotic systems.
TLDR
It is shown that, for individual trajectories, information can be accurately inferred by the number of first-passage times through a given turbulent phase-space cell, which enables us to calculate far more efficiently Lyapunov exponents for such systems. Expand

TLDR
It is given a simple proof that infinite measure implies universal Mittag-Leffler statistics of observables, rather than narrow distributions typically observed in finite measure ergodic maps. Expand
Cycles, randomness, and transport from chaotic dynamics to stochastic processes.
TLDR
With methods from dynamical systems theory, the microscopic time-reversal symmetry can be shown to be broken at the statistical level of description in nonequilibrium systems, and the thermodynamic entropy production turns out to be related to temporal disorder and its time asymmetry away from equilibrium.

Slow Lévy flights.
TLDR
It is shown that Lévy laws, as well as Gaussian distributions, can also be the limit distributions of processes with long-range memory that exhibit very slow diffusion, logarithmic in time. Expand
Explicit Time-Dependent Entropy Production Expressions: Fractional and Fractal Pesin Relations
In this contribution, we present for the first time, explicit expressions for time-dependent entropy production, in the classical context. Here, we pursue the understanding of the time dependence ofExpand

Lyapunov statistics and mixing rates for intermittent systems.
TLDR
It is demonstrated that a recent conjecture stating that correlation functions and tail probabilities of finite time Lyapunov exponents would have the same power law decay in weakly chaotic systems fails for a generic class of maps of the Pomeau-Manneville type. Expand

It is found that the adoption of a nonextensive approach does not serve any predictive purpose: It does not even signal a transition from a stationary to a nonstationary regime. Expand

TLDR
New semiphenomenological arguments are presented which enable us to map the dynamical system near the chaos border onto the effective "ultrametric diffusion" on the boundary of a treelike space with hierarchically organized transition rates. Expand

TLDR
It is shown that intermittent systems of Manneville as well as some countable Markov chains may be sporadic and, furthermore, that the dynamical fluctuations of these systems may be of Lévy's type rather than Gaussian. Expand
