Weak Pullback Attractors of Non-autonomous Difference Inclusions [PDF]

open access: yesJournal of Difference Equations and Applications, 2003
Weak pullback attractors are defined for non-autonomous difference inclusions and their existence and upper semi continuous convergence under perturbation is established. Unlike strong pullback attractors, invariance and pullback attraction here are required only for (at least) a single trajectory rather than all trajectories at each starting point ...

Pullback attractor of a non-autonomous order-2γ parabolic equation for an epitaxial thin film growth model

open access: yesBoundary Value Problems, 2020
The non-autonomous order-2γ parabolic partial differential equation for an epitaxial thin film growth model with dimension d = 3 $d=3$ is investigated by the method of uniform estimates.

Pullback attractor for a dynamic boundary non-autonomous problem with Infinite delay [PDF]

open access: yes, 2018
In this work we prove the existence of solution for a p-Laplacian non-autonomous problem with dynamic boundary and infinite delay. We ensure the existence of pullback attractor for the multivalued process associated to the non-autonomous problem we are ...

Dynamics of a non-autonomous incompressible non-Newtonian fluid with delay [PDF]

open access: yes, 2017
We first study the well-posedness of a non-autonomous incompressible non-Newtonian fluid with delay. The existence of global solution is obtained by classical Galerkin approximation and the energy method.

Robustness of time-dependent attractors in H1-norm for nonlocal problems [PDF]

open access: yes, 2018
In this paper, the existence of regular pullback attractors as well as their upper semicontinuous behaviour in H1-norm are analysed for a parameterized family of non-autonomous nonlocal reaction-diffusion equations without uniqueness, improving previous ...
