Curves in the lightlike cone
The author studies curves in the light-like cone in the Minkowski space of arbitrary dimension. Having fixed the coordinate system, the author obtains several conformal invariants of such curves. In a specialization to the 2-dimensional and 3-dimensional case some results are also obtained, e.g., the author characterizes the Bertrand curves in \(Q^{2}\) and finds a ``normal form'' of some of suche curves in \(Q^{3}\).
