Global existence of strong solutions to the multi-dimensional inhomogeneous incompressible MHD equations

扫码查看
This paper is concerned with the Cauchy problem of the multi-dimensional incompressible magnetohydrodynamic equations with inhomogeneous density and fractional dissipation. It is shown that when alpha+beta-1 + n/2 satisfying 1 <=beta <=alpha <= min{ 3 beta/2 , n/2 , 1 + n/4 } and max { n/4 , n +1/6 } < alpha for n >= 3 , the inhomogeneous incompressible MHD equations have a unique global strong solution for the initial data in some Sobolev spaces without requiring small conditions.
