Multiple-scale analysis and renormalization for pre-asymptotic scalar transport
A. Mazzino, S. Musacchio, A. Vulpiani
Pre-asymptotic transport of a scalar quantity passively advected by a velocity field formed by a large-scale component superimposed to a small-scale fluctuation is investigated bot…
Introduction to chaos and diffusion
G. Boffetta, G. Lacorata, A. Vulpiani
This contribution is relative to the opening lectures of the ISSAOS 2001 summer school and it has the aim to provide the reader with some concepts and techniques concerning chaotic…
The production rate of the coarse grained Gibbs entropy and the Kolmogorov-Sinai entropy: a real connection ?
Massimo Falcioni, Luigi Palatella, Angelo Vulpiani
We discuss the connection between the Kolmogorov-Sinai entropy, , and the production rate of the coarse grained Gibbs entropy, . Detailed numerical computations show t…
Complexity Characterization of Dynamical Systems Through Predictability
Fabio Cecconi, Massimo Falcioni, Angelo Vulpiani
Some aspects of the predictability problem in dynamical systems are reviewed. The deep relation among Lyapunov exponents, Kolmogorov-Sinai entropy, Shannon entropy and algorithmic…
Polymer transport by laminar flows
M. De Lucia, A. Mazzino, A. Vulpiani
Polymer transport is investigated for two paradigmatic laminar flows having open and closed streamlines, respectively. For both types of flows we find transport depletion owing to…
