Upper-semicontinuity of the global attractors for a class of nonlocal Cahn-Hilliard equations [PDF]

open access: yesarXiv, 2018
The aim of this work is to examine the upper-semicontinuity properties of the family of global attractors admitted by a non-isothermal viscous relaxation of some nonlocal Cahn-Hilliard equations. We prove that the family of global attractors is upper-semicontinuous as the perturbation parameters vanish.

Pullback D-Attractor of Coupled Rod Equations with Nonlinear Moving Heat Source

open access: yesJournal of Applied Mathematics, 2014
We consider the pullback D-attractor for the nonautonomous nonlinear equations of thermoelastic coupled rod with a nonlinear moving heat source. By Galerkin method, the existence and uniqueness of global solutions are proved under homogeneous boundary ...

Exponential attractors for a Cahn-Hilliard model in bounded domains with permeable walls

open access: yesElectronic Journal of Differential Equations, 2006
In a previous article [7], we proposed a model of phase separation in a binary mixture confined to a bounded region which may be contained within porous walls. The boundary conditions were derived from a mass conservation law and variational methods.

Global Attractors of the Extensible Plate Equations with Nonlinear Damping and Memory

open access: yesJournal of Function Spaces, 2017
We prove in this paper the existence of a global attractor for the plate equations of Kirchhoff type with nonlinear damping and memory using the contraction function method.

Existence of the global attractor for the plate equation with nonlocal nonlinearity in R^{n} [PDF]

open access: yesarXiv, 2015
We consider Cauchy problem for the semilinear plate equation with nonlocal nonlinearity. Under mild conditions on the damping coefficient, we prove that the semigroup generated by this problem possesses a global attractor.

Global attractor of the extended Fisher-Kolmogorov equation in Hk spaces

open access: yesBoundary Value Problems, 2011
The long-time behavior of solution to extended Fisher-Kolmogorov equation is considered in this article. Using an iteration procedure, regularity estimates for the linear semigroups and a classical existence theorem of global attractor, we prove that the

The finite dimensions and determining modes of the global attractor for 2d Boussinesq equations with fractional Laplacian [PDF]

open access: yesarXiv, 2016
In this article, we prove the finite dimensionality of the global attractor and estimate the numbers of the determining modes for the 2D Boussinesq system in a periodic channel with fractional Laplacian in subcritical case.

Global attractor for an equation modelling a thermostat

open access: yesElectronic Journal of Differential Equations, 2003
In this work we show that the system considered by Guidotti and Merino in [2] as a model for a thermostat has a global attractor and, assuming that the parameter is small enough, the origin is globally asymptotically stable.
