Appl. Math. Comput. 182, No. 1, 610-620 (2006).

Summary: This paper is concerned with the existence and regularity of global attractors of micropolar fluid flows in two-dimensional unbounded domains, in which the Poincaré inequality holds. Based on an asymptotic compactness argument, a \(L^{2}\) global attractor is shown to exist if the stationary external vector field is in \(H^{ - 1}\). Moreover, if the external vector field is in \(L^{2}\), then the \(L^{2}\) global attractor becomes an \(H^{1}\) global attractor.
