Abstract

This paper deals with the 3D incompressible MHD equations with density-dependent viscosity in bounded domain. The global well-posedness of strong solutions is established in the vacuum cases, provided the assumption that $${\bar{\rho }}+\Vert H_0\Vert _{L^3}$$ is suitably small with large velocity, which extends the recent work (Song in Z Angew Math Phys 69(2):23, 2018) to the global one. Furthermore, the exponential decay of the solution is also obtained.
