Pullback attractors of nonautonomous and stochastic multivalued dynamical systems

open access: yesSet-valued Analysis, 2003
In this paper we study the existence of pullback global attractors for multivalued processes generated by differential inclusions. First, we define multivalued dynamical processes, prove abstract results on the existence of !-limit sets and global attractors and study their topological properties (compactness, conectedness).

Synchronization of nonautonomous dynamical systems

open access: yesElectronic Journal of Differential Equations, 2003
The synchronization of two nonautonomous dynamical systems is considered, where the systems are described in terms of a skew-product formalism, i.

Pullback attractor of a nonautonomous fourth-order parabolic equation modeling epitaxial thin film growth

open access: yesElectronic Journal of Differential Equations, 2015
We study a nonautonomous fourth-order parabolic equation modeling epitaxial thin film growth. It is shown that a pullback attractor of the model exists when the external force has exponential growth.

Pullback Attractors for Nonautonomous 2D-Navier-Stokes Models with Variable Delays

open access: yesAbstract and Applied Analysis, 2013
Using a method based on the concept of the Kuratowski measure of the noncompactness of a bounded set as well as some new estimates of the equicontinuity of the solutions, we prove the existence of a unique pullback attractor in higher regularity space ...

Approximate Kelvin-Voigt Fluid Driven by an External Force Depending on Velocity with Distributed Delay

open access: yesDiscrete Dynamics in Nature and Society, 2015
We consider the approximate 3D Kelvin-Voigt fluid driven by an external force depending on velocity with distributed delay. We investigate the long time behavior of solutions to Navier-Stokes-Voigt equation with a distributed delay external force ...
