Convergence to local random attractors [PDF]

open access: yesDynamical Systems, 2003
Random attractors allow one to classify qualitative and quantitative aspects of the long-time behaviourof stochastically forced systems viewed as random dynamical systems (RDS) in an analogous way to attractors for deterministic systems. We compare several notions of random attractor in RDS by examining convergence of trajectories to a random invariant

Connectedness of random set attractors [PDF]

open access: yesRendiconti Lincei, Matematica e Applicazioni, 2018
We examine the question whether random set attractors for continuous-time random dynamical systems on a connected state space are connected. In the deterministic case, these attractors are known to be connected. In the probabilistic setup, however, connectedness has only been shown under stronger connectedness assumptions on the ...

Upper semicontinuity of random attractors for non-compact random dynamical systems [PDF]

open access: yesElectronic Journal of Differential Equations, 2009
The upper semicontinuity of random attractors for non-compact random dynamical systems is proved when the union of all perturbed random attractors is precompact with probability one.

Upper Semicontinuity of Attractors for a Non-Newtonian Fluid under Small Random Perturbations [PDF]

open access: yesAbstract and Applied Analysis, 2014
This paper investigates the limiting behavior of attractors for a two-dimensional incompressible non-Newtonian fluid under small random perturbations. Under certain conditions, the upper semicontinuity of the attractors for diminishing perturbations is ...

Comment on: Criteria for Strong and Weak Random Attractors [PDF]

open access: yesJournal of Dynamics and Differential Equations
Abstract In the article ’Criteria for Strong and Weak Random Attractors’ necessary and sufficient conditions for strong attractors and weak attractors are studied. In this note we correct two of its theorems on strong attractors.
