Zero constant mean curvature in Minkowski space versus in Euclidean space












0












$begingroup$


There's a famous result in $mathbb{R}^3$ which goes as: there are no compact minimal surfaces in $mathbb{R}^3$.So the mean curvature cannot be zero in compact surfaces in $mathbb{R}^3$. Now what's the intuition behind why that isn't true in the Minkowski space $E_1^3$ (also known as $mathbb{L}^3$)?
