In the Lorentzian space, a regular curve is called time-like, space-like and null curve according to velocity vector's status [3], [6]. In this paper, we obtained the Harmonic curvatures for a regular curve in the Lorentzian space. We also obtained the relationship between the harmonic curvatures and their own derivations.
