Robust exponential attractors for singularly perturbed phase-field type equations [PDF]

open access: yesElectronic Journal of Differential Equations, 2002
In this article, we construct robust (i.e. lower and upper semicontinuous) exponential attractors for singularly perturbed phase-field type equations. Moreover, we obtain estimates for the symmetric distance between these exponential attractors and that ...

Pullback Exponential Attractors for Parabolic Equations with Dynamical Boundary Conditions [PDF]

open access: yesTaiwanese Journal of Mathematics, 2017
The existence of pullback exponential attractors for a nonautonomous semilinear parabolic equation with dynamical boundary condition is proved when the timedependent forcing terms are translation bounded or even grow exponentially in the past and in the ...

Robust family of exponential attractors for isotropic crystal models

open access: yes, 2016
Our aim in this paper is to study, in term of finite dimensional exponential attractors, the Willmore regularization, (depending on a small regularization parameter β > 0), of two phase‐field equations, namely, the Allen–Cahn and the Cahn–Hilliard ...

GLOBAL AND EXPONENTIAL ATTRACTORS FOR THE PENROSE–FIFE SYSTEM [PDF]

open access: yesMathematical Models and Methods in Applied Sciences, 2009
The Penrose–Fife system for phase transitions is addressed. Dirichlet boundary conditions for the temperature are assumed. Existence of global and exponential attractors is proved. Differently from preceding contributions, here the energy balance equation is both singular at 0 and degenerate at ∞.

Pullback exponential attractors for evolution processes in Banach spaces: Properties and applications [PDF]

open access: yes, 2013
This article is a continuation of our previous work [5], where we formulated general existence theorems for pullback exponential attractors for asymptotically compact evolution processes in Banach spaces and discussed its implications in the ...

Pullback and uniform exponential attractors for non-autonomous Oregonator systems

open access: yesOpen Mathematics
We consider the long-time global dynamics of non-autonomous Oregonator systems. This system is a coupled system of three reaction-diffusion equations, that arises from the Belousov-Zhabotinskii reaction.

Exponential attractors for two-dimensional nonlocal diffusion lattice systems with delay

open access: yesCommunications on Pure & Applied Analysis, 2022
In this paper, we study the long term dynamical behavior of a two-dimensional nonlocal diffusion lattice system with delay. First some sufficient conditions for the construction of an exponential attractor are presented for infinite dimensional ...

Uniform Exponential Attractors for Non-Autonomous Strongly Damped Wave Equations

open access: yes, 2014
In this paper, we study the existence of exponential attractors for strongly damped wave equations with a time-dependent driving force. To this end, the uniform H?lder continuity is established to the variation of the process in the phase apace.
