Minimality properties of set-valued processes and their pullback attractors [PDF]

open access: green, 2014
We discuss the existence of pullback attractors for multivalued dynamical systems on metric spaces. Such attractors are shown to exist without any assumptions in terms of continuity of the solution maps, based only on minimality properties with respect ...

Existence of pullback attractors for pullback asymptotically compact processes [PDF]

open access: greenNonlinear Analysis: Theory, Methods & Applications, 2009
This paper is concerned with the existence of pullback attractors for evolution processes. Our aim is to provide results that extend the following results for autonomous evolution processes (semigroups) i) An autonomous evolution process which is bounded dissipative and asymptotically compact has a global attractor.

Existence and upper semicontinuity of pullback attractors for Kirchhoff wave equations in time-dependent spaces [PDF]

open access: greenDiscrete and Continuous Dynamical Systems. Series A
In this paper, we shall investigate the existence and upper semicontinuity of pullback attractors for non-autonomous Kirchhoff wave equations with a strong damping in the time-dependent space $X_t$.

Upper semi-continuity of pullback attractors for bipolar fluids with delay

open access: goldElectronic Research Archive, 2023
We investigate bipolar fluids with delay in a $ 2D $ channel $ \Sigma = \mathbb{R}\times (-K, K) $ for some $ K > 0 $. The channel $ \Sigma $ is divided into a sequence of simply connected, bounded, and smooth sub-domains $ \Sigma_n (n = 1, 2, 3\cdot ...

Pullback attractors for a singularly nonautonomous plate equation [PDF]

open access: yesElectronic Journal of Differential Equations, 2010
We consider the family of singularly nonautonomous plate equation with structural damping \[ u_{tt} + a(t,x)u_{t} + (- \Delta) u_{t} + (-\Delta)^{2} u + \lambda u = f(u), \] in a bounded domain $\Omega \subset \R^n$, with Navier boundary conditions. When

Pullback attractors for non-autonomous Bresse systems

open access: yesElectronic Journal of Differential Equations, 2022
This article concerns the asymptotic behavior of solutions of non-autonomous Bresse systems. We establish the existence of pullback attractor and upper semicontinuity of attractors as a non-autonomous perturbations tend to zero.

Convergences of asymptotically autonomous pullback attractors towards semigroup attractors

open access: diamondDiscrete & Continuous Dynamical Systems - B, 2018
For pullback attractors of asymptotically autonomous dynamical systems we study the convergences of their components towards the global attractors of the limiting semigroups. We use some conditions of uniform boundedness of pullback attractors, instead of uniform compactness conditions used in the literature.
