ABSTRACT OF THE TALK

In this paper, we consider the global existence and uniqueness of the solutions to the 2D viscous, non-resistive MHD system. For any initial data, if the background magnetic field is sufficiently large, then we can obtain the global strong solutions.
$\left\{ \begin{align}
& {{\partial }_{t}}b+v\cdot \nabla b=b\cdot \nabla v,\ \ \ \left( t,x \right)\in {{\mathbb{R}}^{+}}\times {{\mathbb{R}}^{2}}, \\
& {{\partial }_{t}}v+v\cdot \nabla v-\Delta v+\nabla p=b\cdot \nabla b, \\
& \text{div}v=\text{div}b=0, \\
& b\left| _{t=0}={{b}_{0}},\ \ v\left| _{t=0}={{v}_{0}}, \right. \right. \\
\end{align} \right.$
$v\left( t,x \right)\to 0,b\left( t,x \right)\to {{\left( \frac{1}{\varepsilon },0 \right)}^{\text{T}}},\text{when}\left| x \right|\to \infty ,$
