Some Characterization of Lorentzian Spherical Spacelike Curves with the Timelike and the Null Principal Normal


Miroslava Petrović-Torgašev, Emilija Šućurović




In [4] the authors have characterized Lorentzian spherical spacelike curves in the 3-dimensional Minkowski space with the spacelike normal. In this paper, we shall characterize the Lorentzian spherical spacelike curves in the same space with the timelike and the null principal normal.
