Abstract
In this paper, we establish the global existence of mild solutions to the n-dimensional generalized MHD system provided that the norms of the initial data are bounded exactly by the minimal value of the viscosity coefficients and the fractional powers. In addition, we also establish the existence of the global small solution in the Fourier–Herz spaces. Finally, we prove the long time decay of the global solutions in the corresponding spaces.
