文摘In this article, we study the regularity of weak solutions and the blow-up criteria for smooth solutions to the magneto-micropolar fluid equations in R3. We obtain the classical blow-up criteria for smooth solutions (u,w, b), i.e., u ∈ Lq(0, T; LP(R3) for 2/q+3/P≤ 1with 3〈P≤∞,u∈C([0,T);L3(R3))or△u∈Lq(0,T,LP)for 3/2〈P≤∞ satisfying 2/q+3/P≤ 2. Moreover, our results indicate that the regularity of weak solutions is dominated by the velocity u of the fluid. In the end-point case p = ∞, the blow-up criteriacan be extended to more general spaces △u E L1 (0, T; B0∞,∞(R3).
