چکیده
|
We consider one-parameter null hypersurfaces associated with spacelike curves. the spacelike curves are in anti-de sitter 3-space while one-parameter null hypersurfaces lie in 4-dimensional semi-euclidean space with index 2. we classify the generic singularities of the hypersurfaces,which are cuspidal edges and swallowtails. and we reveal the geometric meanings of the singularities of such hypersurfaces by the singularity theory. © 2016 yongqiao wang et al.
