Some characterizations of the Lorentzian spherical timeline and null curves
Miroslava Petrović-Torgašev and Emilija Šućurović

Abstract

In [5] and [6] the authors have characterized the Lorentzian spherical spacelike curves in the Minkowski $3$-space $E_1^3$. In this paper, we shall characterize the Lorentzian spherical timelike and null curves in the same space.
