Analyticity estimates for the 3D magnetohydrodynamic equations.

This paper was concerned with the Cauchy problem of the 3D magnetohydrodynamic (MHD) system. We first proved that this system was local well-posed with initial data in the Besov space , in the critical Besov space , and in with , respectively. We also obtained a new growth rate estimates for the analyticity radius. [ABSTRACT FROM AUTHOR]
