Özet
In this paper, we investigate the representation of curves on the lightlike cone Q(2)(3) in Minkowski space R-2(4) by structure functions. In addition, with this representation, we classify all of the null curves on the lightlike cone Q(2)(3) in four types, and we obtain a natural Frenet frame for these null curves. Furthermore, for this natural Frenet frame, we calculate curvature functions of a null curve, especially the curvature function kappa(2)=0, and we show that any null curve on the lightlike cone is a helix. Finally, we find all curves with constant curvature functions.
