Abstract:
This article concerns the asymptotic behavior of solutions
to the two-dimensional Navier-Stokes equations with both
non-autonomous deterministic and stochastic terms defined on
unbounded domains. First we introduce a continuous cocycle
for the equations and then prove the existence and uniqueness
of tempered random attractors.
We also characterize the structures of the random attractors
by complete solutions. When deterministic forcing terms are periodic,
we show that the tempered random attractors are also periodic.
Since the Sobolev embeddings on unbounded domains are not compact,
we establish the pullback asymptotic compactness of solutions by
Ball's idea of energy equations.
