On partially null and pseudo null curves in the semi-euclidean space $$ R^{4}_{2} $$

open access: yesJournal of Geometry, 2006
In this paper, we obtain the Frenet equations of a pseudo null and a partially null curves, lying fully in the semi–Euclidean space $$ R^{4}_{2} $$ , and classify all such curves with constant curvatures.
