In this paper we study the magneto-micropolar fluid equations in R3,
prove the existence of the strong solution with initial data in Hs(R3) for
s>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,ω,b) which relies on the
vorticity of velocity ∇×u only.Comment: 19page
