Pullback exponential attractors

open access: yesDiscrete and Continuous Dynamical Systems, 2010
In this work, we show how to construct a pullback exponential attractor associated with an infinite dimensional dynamical system, i.e., a family of time dependent compact sets, with finite fractal dimension, which are positively invariant and exponentially attract in the pullback sense every bounded set of the phase space.

Exponential Attractor for a First-Order Dissipative Lattice Dynamical System

open access: yesJournal of Applied Mathematics, 2008
We construct an exponential attractor for a first-order dissipative lattice dynamical system arising from spatial discretization of reaction-diffusion equations in ℝ𝑘. And we obtain fractal dimension of the exponential attractor.

Exponential Attractors for a Doubly Nonlinear Equation

open access: yesJournal of Mathematical Analysis and Applications, 1994
The authors investigate the following scalar PDE: \[ \partial_ t \beta (u) = \Delta u - g(x,u) \quad \text{on} \quad \mathbb{R}_ + \times \Omega \tag{1} \] with \(u=0\) on \(\mathbb{R}_ + \times \partial \Omega\) and \(\beta (u(0,x)= \beta (u_ 0(x))\) for \(x \in \Omega\) for some given \(u_ 0\). Here \(\Omega \subseteq \mathbb{R}^ d\) with \(d \leq 3\)

Chaotic systems with variable indexs for image encryption application

open access: yesScientific Reports, 2022
A new chaotic system is obtained by changing the number of unknown parameters. The dynamical behavior of the chaotic system is investigated by the exponential change of the single unknown parameter and the state variable in the nonlinear term of the ...

Pullback Exponential Attractor for Second Order Nonautonomous Lattice System

open access: yesDiscrete Dynamics in Nature and Society, 2014
We first present some sufficient conditions for the existence of a pullback exponential attractor for continuous process on the product space of the weighted spaces of infinite sequences.

Exponential attractor for Kirchhoff model with time delay and thermal effect

open access: yesResults in Applied Mathematics, 2023
The Kirchhoff model is derived from the vibration problem of stretchable strings. In this paper, we focus on the long-time dynamics of the Kirchhoff model with time delay and thermal effect.

Chevron Pattern Equations: Exponential Attractor and Global Stabilization [PDF]

open access: yesVietnam Journal of Mathematics, 2021
The initial boundary value problem for a nonlinear system of equations modeling the chevron patterns is studied in one and two spatial dimensions. The existence of an exponential attractor and the stabilization of the zero steady state solution through application of a finite-dimensional feedback control is proved in two spatial dimensions.

Exponential Attractor for the Boussinesq Equation with Strong Damping and Clamped Boundary Condition

open access: yesDiscrete Dynamics in Nature and Society, 2016
The paper studies the existence of exponential attractor for the Boussinesq equation with strong damping and clamped boundary condition utt-Δu+Δ2u-Δut-Δg(u)=f(x). The main result is concerned with nonlinearities g(u) with supercritical growth.
