Slow invariant manifolds as curvature of the flow of dynamical systems [PDF]

open access: yes, 2014
Considering trajectory curves, integral of n-dimensional dynamical systems, within the framework of Differential Geometry as curves in Euclidean n-space, it will be established in this article that the curvature of the flow, i.e.

Differentiable dynamical systems and the problem of turbulence [PDF]

open access: yesBulletin of the American Mathematical Society, 1981
Summary: The paper is a review presented at the Symposium on the Mathematical Heritage of Henry Poincaré in 1980. The author discusses different theories of turbulence. He explains the way dynamical systems appear in the study of Navier-Stokes equation and describes the connection between the turbulence and the ``strange'' attractors theory. The author

Lectures on Structural Stability in Dynamics

open access: yes, 2017
These lectures present results and problems on the characterization of structurally stable dynamics. We will shed light those which do not seem to depend on the regularity class (holomorphic or differentiable).

Lyapunov exponent for Lipschitz maps

open access: yes, 2018
It is well-known that the Lyapunov exponent plays a fundamental role in dynamical systems. In this note, we propose an alternative definition of Lyapunov exponent in terms of Lipschitz maps, which are not necessarily differentiable.

Ergodicity of a Generalized Jacobi's Equation and Applications [PDF]

open access: yes, 2015
Consider a $1$-dimensional centered Gaussian process $W$ with $\alpha$-H\"older continuous paths on the compact intervals of $\mathbb R_+$ ($\alpha\in ]0,1[$) and $W_0 = 0$, and $X$ the local solution in rough paths sense of Jacobi's equation driven by ...

On Differentiation and Homeostatic Behaviours of Boolean Dynamical Systems [PDF]

open access: yes, 2006
We study rules proposed by the biologist R. Thomas relating the structure of a concurrent system of interacting genes (represented by a signed directed graph called a regulatory graph) with its dynamical properties. We prove that the results in [10] are stable under projection, and this enables us to relax the assumptions under which they are valid ...

Computing covariant vectors, Lyapunov vectors, Oseledets vectors, and dichotomy projectors: a comparative numerical study

open access: yes, 2012
Covariant vectors, Lyapunov vectors, or Oseledets vectors are increasingly being used for a variety of model analyses in areas such as partial differential equations, nonautonomous differentiable dynamical systems, and random dynamical systems.

A stochastic-hydrodynamic model of halo formation in charged particle beams [PDF]

open access: yes, 2003
The formation of the beam halo in charged particle accelerators is studied in the framework of a stochastic-hydrodynamic model for the collective motion of the particle beam.
