A note on the spherical images of W-partially null curves in Minkowski space-time E-1(4)

Abstract

In this study, we investigate the tangent, principal normal and trinormal spherical images of a W-partially null curve in pseudohyperbolic space H-0(3) of Minkowski space time E-1(4). The tangent, principal normal spherical images of a W-partially null curve occur as spacelike curves lying in pseudosphere S-0(3), then the Frenet-Serret invariants of the mentioned image curves are obtained in terms of the invariants of W-partially null curve. The trinormal spherical images of a W-partially null curve occur as spacelike curves lying in pseudohyperbolic space H-0(3), then the Frenet-Serret invariants of the mentioned image curves are obtained in terms of the invariants of W-partially null curve. Finally, we give some characterizations of the spherical images being helices.
