Normal spacelike developable surfaces on Minkowski 3-space
Ibrahim Al-Dayela,*, Emad Soloumaa,b
ABSTRACT: In this paper, we introduce a normal spacelike developable surface that is normal to a surface ? along a
spacelike curve ? in Minkowski 3-space R
3
1
. We study the existence and singularities of normal spacelike developable
surface through two invariants of the spacelike curves on a surface. Furthermore, we will be interested in the case
when the spacelike curve is a geodesic curve and when it lies on a surface of revolution.
