Also, we obtain a characterization such as: The curve alpha is a null W-n - slant helix <=>H-n(') - k(1)H(n-3) = 0 where H-n, Hn-1 and Hn-3 are harmonic curvature functions and k(1), k(2) are the Cartan curvature functions of the null curve alpha.eninfo:eu-repo/semantics/openAccessNull CurveSlant HelicesHarmonic Curvature FunctionsLorentzian (N + 2)-SpaceArticle563100310162-s2.0-85014964028Q3WOS:00040698010002910.5666/KMJ.2016.56.3.1003
