Global well-posedness for radial extremal hypersurface equation in $\left(1+3\right)$-dimensional Minkowski space-time in critical Sobolev space

Sheng Wang, Yi Zhou

In this article, we prove the global well-posedness in the critical Sobolev space $H_{rad}^2\left({\mathbb{R}}^2\right)\times H_{rad}^1\left({\mathbb{R}}^2\right)$ for the radial tim…
