Abstract
In this paper, we consider the asymptotic behaviour of the solution for a damped Rosenau equation on . We apply a variant of Riesz–Rellich criteria, which involves the Littlewood–Paley projection operators, to prove that the damped Rosenau equation possesses a global attractor
in
for any
. Moreover, the global attractor
is contained in
, if the time-independent source term is in
and the initial data are in
. Our results establish the regularity of the global attractor for the damped Rosenau equation in fractional order Sobolev space, which is a new ingredient in this paper.
