Global existence of strong solutions to the multi-dimensional inhomogeneous incompressible MHD equations
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 \(\alpha+\beta=1+\frac{n}{2}\) satisfying \(1\leq \beta\leq \alpha\leq\min \{\frac{3\beta}{2},\frac{n}{2}...

Summary: | 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 \(\alpha+\beta=1+\frac{n}{2}\) satisfying \(1\leq \beta\leq \alpha\leq\min \{\frac{3\beta}{2},\frac{n}{2},1+\frac{n}{4}\}\) and \(\frac{n}{4}<\alpha\) for \(n\geq3\) , then the inhomogeneous incompressible MHD equations has a unique global strong solution for the initial data in Sobolev space which do not need a small condition. |
