Abstract : In this paper, we define the directional associated curve and the self-associated curve of a null curve in Minkowski 3-space. We study the properties and relations between the null curve, its directional associated curve and its self-associated curve. At the same time, by solving certain differential equations, we get the explicit representations of some null curves.
Keywords : Minkowski space, null curve, null curvature, directional associated curve, self-associated curve
