Null W-slant helices in

In this paper, we give the necessary and sufficient conditions for null curves in E 1 3 to be W-slant helix in terms of their curvature functions. Mainly, throughout this paper relationships between the null W-slant helices and their pseudo spherical images are obtained. Furthermore, some illustrative examples of the null W-slant helices and their pseudo spherical indicatrices in E 1 3 are demonstrated.
