RANDOM ATTRACTORS FOR NON-AUTONOMOUS STOCHASTIC NAVIER-STOKES-VOIGT EQUATIONS IN SOME UNBOUNDED DOMAINS

. This paper is concerned with the asymptotic behavior for the three dimensional non-autonomous stochastic Navier-Stokes-Voigt equations on unbounded domains. A continuous non-autonomous random dynamical system for the equations is firstly established. We then obtain pullback asymptotic compactness of solutions and prove that the existence of tempered random attractors for the random dynamical system generated by the equations. Furthermore, we obtain that the tempered random attractors are periodic when the deterministic non-autonomous external term is periodic in time.
