Existence theorem and blow-up criterion of the strong solutions to the magneto-micropolar fluid equations.
(English)
[J] Math. Methods Appl. Sci. 31, No. 9, 1113-1130 (2008). ISSN 0170-4214; ISSN 1099-1476/e

Summary: We study the magneto-micropolar fluid equations in $\mathbb R^{3}$, prove the existence of strong solution with initial data in $H^s(\mathbb R^3)$ for $s> \frac 3 2$, and set up its blow-up criterion. The tool we mainly use is Littlewood-Paley decomposition, by which we obtain a Beale-Kato-Majda-type blow-up criterion for smooth solution $(u,\omega , b)$ that relies on the vorticity of velocity $\nabla \times u$ only.
