The Bi-normal fields on spacelike surfaces in $R_{1}^{4}$

Dang Van Cuong

A normal field on a spacelike surface in $R_{1}^{4}$ is called bi-normal if $K^{ν}$ , the determinant of Weingarten map associated with $ν$ , is zero. In this paper we give a relationship…

$H S_{r}$ -valued Gauss maps and umbilic spacelike surfaces of codimension two

Dang Van Cuong, Doan The Hieu

To study spacelike surfaces of codimension two in the Lorentz-Minkowski space $R_{1}^{n + 1},$ we construct a pair of maps whose values are in $HS_r:=H_+^n(\textbf v,1)\cap \{x_{n…
