Geometrical Properties of the Pseudonull Hypersurfaces in Semi-Euclidean 4-Space.

In this paper, we focus on some geometrical properties of the partially null slant helices in semi-Euclidean 4-space. By structuring suitable height functions, we obtain the singularity types of the pseudonull hypersurfaces, which are generated by the partially null slant helices. An example is given to determine the main results. [ABSTRACT FROM AUTHOR]
