Abstract: | We consider the micropolar fluid system in a bounded domain of
and prove the existence and the uniqueness of a global strong solution with initial data being a perturbation of the stationary
solution, whose existence is also obtained. We prove that these solutions converge uniformly to the stationary solutions with
exponential decay rate. The technique of our analysis is the semigroups approach in L
p
-spaces.
