Blow-up criterion for 3D compressible viscous magneto-micropolar fluids with initial vacuum

In this paper, the author establishes a blow- up criterion of strong solutions to 3D compressible viscous magneto- micropolar fluids. It is shown that if the density and the velocity satisfy parallel to rho parallel to(L infinity(O,T;L infinity)) + parallel to u parallel to(Ls(O, T; Lr)) < infinity, where 2/s + 3/r <= 1 and 3 < r <= infinity, then the strong solutions to the Cauchy problem can exist globally over R-3 x [0,T]. The initial density may vanish on open sets, that is, the initial vacuum is allowed.
