Existence and upper semicontinuity of random attractors for stochastic p-Laplacian equations on unbounded domains

Electronic Journal of Differential Equations, 2014
The existence of a pullback attractor is established for a stochastic p-Laplacian equation on $\mathbb{R}^n$. Furthermore, the limiting behavior of random attractors of the random dynamical systems as stochastic perturbations approach zero is studied ...

Existence and regularity of pullback attractors for a 3D non-autonomous Navier–Stokes–Voigt model with finite delay

Electronic Journal of Qualitative Theory of Differential Equations
In this manuscript previous results [Nonlinearity 25(2012), 905–930] are extended to a non-autonomous 3D Navier–Stokes–Voigt model in which a forcing term contains memory effects.

Bi-space pullback attractors for closed processes

The São Paulo Journal of Mathematical Sciences, 2012
In the description of the long-time behavior of solutions to nonautonomous differential equations the notion of a pullback attractor plays a similar role as the global attractor in autonomous dynamical systems. We present the theorem on the existence of a pullback attractor if the evolution process is a family of closed operators.

Pullback attractors for non-autonomous parabolic equations involving Grushin operators

Electronic Journal of Differential Equations, 2010
Using the asymptotic a priori estimate method, we prove the existence of pullback attractors for a non-autonomous semilinear degenerate parabolic equation involving the Grushin operator in a bounded domain.

Lower semicontinuity of pullback attractors for a singularly nonautonomous plate equation

Electronic Journal of Differential Equations, 2012
We show the lower semicontinuity of the family of pullback attractors for the 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 the energy space $H^2_0(
