$LS_{\lowercase {r}}$-valued Gauss maps and spacelike surfaces of revolution in ${\mathbb{R}}_1^4$

Dang Van Cuong

To study spacelike surfaces in the Lorentz-Minkowski space ${\mathbb{R}}_1^4,$ we construct a pair of maps whose values are in the lightcone, called ${\mathfrak{l}}_r^{\pm }$-Gauss maps.…
