Continuity of pullback and uniform attractors [PDF]

open access: yesJournal of Differential Equations, 2018
We study the continuity of pullback and uniform attractors for non-autonomous dynamical systems with respect to perturbations of a parameter. Consider a family of dynamical systems parameterised by a complete metric space $ $ such that for each $ \in $ there exists a unique pullback attractor $\mathcal A_ (t)$. Using the theory of Baire category we

Backwards Asymptotically Autonomous Dynamics for 2D MHD Equations

open access: yesDiscrete Dynamics in Nature and Society, 2018
We consider the backwards topological property of pullback attractors for the nonautonomous MHD equations. Under some backwards assumptions of the nonautonomous force, it is shown that the theoretical existence result for such an attractor is derived ...

Time-Dependent Attractor for the Oscillon Equation [PDF]

open access: yes, 2010
We investigate the asymptotic behavior of the nonautonomous evolution problem generated by the Klein-Gordon equation in an expanding background, in one space dimension with periodic boundary conditions, with a nonlinear potential of arbitrary polynomial ...

Pullback attractors for generalized evolutionary systems

open access: yesDiscrete & Continuous Dynamical Systems - B, 2015
We give an abstract framework for studying nonautonomous PDEs, called a generalized evolutionary system. In this setting, we define the notion of a pullback attractor. Moreover, we show that the pullback attractor, in the weak sense, must always exist. We then study the structure of these attractors and the existence of a strong pullback attractor.

Pullback Attractors for Stochastic Young Differential Delay Equations [PDF]

open access: yesJournal of Dynamics and Differential Equations, 2020
We study the asymptotic dynamics of stochastic Young differential delay equations under the regular assumptions on Lipschitz continuity of the coefficient functions. Our main results show that, if there is a linear part in the drift term which has no delay factor and has eigenvalues of negative real parts, then the generated random dynamical system ...

Pullback attractors for asymptotically compact non-autonomous dynamical systems [PDF]

open access: yes, 2006
First, we introduce the concept of pullback asymptotically compact non-autonomous dynamical system as an extension of the similar concept in the autonomous framework.

On attractors, spectra and bifurcations of random dynamical systems [PDF]

open access: yes, 2015
In this thesis a number of related topics in random dynamical systems theory are studied: local attractors and attractor-repeller pairs, the exponential dichotomy spectrum and bifurcation theory.

On the Dynamics of Nonautonomous Parabolic Systems Involving the Grushin Operators

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
We study the long-time behavior of solutions to nonautonomous semilinear parabolic systems involving the Grushin operators in bounded domains. We prove the existence of a pullback D-attractor in (L2(Ω))m for the corresponding process in ...

Dynamics of wave equations with moving boundary [PDF]

open access: yes, 2017
This paper is concerned with long-time dynamics of weakly damped semilinear wave equations defined on domains with moving boundary. Since the boundary is a function of the time variable the problem is intrinsically non-autonomous.
