Exponential Attractors in Generalized Relativistic Billiards

Communications in Mathematical Physics, 2004
A generalized relativistic billiard is the following dynamical system: a particle moves under the influence of some force fields in the interior of a domain with pseudo-Riemannian metric, and as the particle hits the boundary of the domain, its velocity is transformed as if the particle underwent an elastic collision with a moving wall, considered in ...

A uniformly exponential random forward attractor which is not a pullback attractor

Archiv der Mathematik, 2002
The author constructs an example of a random forward attractor for a random dynamical system (RDS) that is not a pullback attractor which is one of 3 possible notions of an attractor one can naturally define for RDS (and which all coincide for deterministic dynamical systems).

Exponential attractors for semigroups in Banach spaces

Nonlinear Analysis: Theory, Methods & Applications, 2012
Abstract Let { S ( t ) } t ⩾ 0 be a semigroup on a Banach space X , and A be the global attractor for { S ( t ) } t ⩾ 0 . We assume that there exists a T ∗ such that S ≜ S ( T ∗ ) is of class C 1 on a bounded absorbing set B ϵ 0

Approximation of exponential order of the attractor of a turbulent flow

Physica D: Nonlinear Phenomena, 1994
We consider the two-dimensional Navier-Stokes equations with periodic boundary conditions, describing the evolution of homogeneous flows. We construct approximate inertial manifolds (AIMs) whose order decreases exponentially fast with respect to the dimension of the manifold. We recall that an AIM is a smooth manifold of solutions \({\mathcal M}\) such

Exponential attractors and their relevance to fluid dynamics systems

Physica D: Nonlinear Phenomena, 1993
This paper investigates the theory of exponential attractors and its significance in infinite dimensional dynamical systems. The authors study a general class of parabolic P.D.E. with emphasis given to the 2D Navier- Stokes equations. Kuramoto-Sivashinsky equation is also studied briefly.

Finite‐dimensional attractors and exponential attractors for degenerate doubly nonlinear equations

Mathematical Methods in the Applied Sciences, 2009
AbstractWe consider the following doubly nonlinear parabolic equation in a bounded domain Ω⊂ℝ3:where the nonlinearityfis allowed to have a degeneracy with respect to ∂tuof the form ∂tu|∂tu|pat some pointsx∈Ω.Under some natural assumptions on the nonlinearitiesfandg, we prove the existence and uniqueness of a solution of that problem and establish the ...

Exponential Decay of Correlations for Nonuniformly Hyperbolic Flows with a $${{C^{1+\alpha}}}$$C1+α Stable Foliation, Including the Classical Lorenz Attractor

, 2015
We prove exponential decay of correlations for a class of $${C^{1+\alpha}}$$C1+α uniformly hyperbolic skew product flows, subject to a uniform nonintegrability condition.

Finite-Dimensional Attractors and Exponential Attractors for the Navier--Stokes Equations of Compressible Flow

SIAM Journal on Mathematical Analysis, 2003
Summary: We prove that the uniform attractor for the Navier-Stokes equations of compressible flow with quasi-periodic external forces has finite fractal dimension. As a byproduct of our analysis, we also obtain the existence of finite-dimensional exponential attractors for the Navier-Stokes system.
