SIMILAR AND SELF-SIMILAR NULL CARTAN CURVES IN MINKOWSKI-LORENTZIAN SPACES.

In this paper, differential invariants of null Cartan curves are studied in (n+2) dimensional Lorentzian similarity geometry. The fundamental theorem for a null Cartan curve in similarity geometry is investigated and the characterization of all self-similar null Cartan curves parameterized by de Sitter parameter in Minkowski space-time is given.
