Classification of zero mean curvature surfaces of separable type in Lorentz-Minkowski space

Seher Kaya, Rafael López

Consider the Lorentz-Minkowski $3$-space ${\mathbb{L}}^3$ with the metric $d{x}^2+d{y}^2-d{z}^2$ in canonical coordinates $(x,y,z)$. A surface in ${\mathbb{L}}^3$ is said to be separable if…
