Özet

In this paper, we define spacelike line congruence, which has the parameter ruled surfaces as principal ruled surfaces, on the dual unit hyperbolic sphere H-+(2) in the dual Lorentzian 3-space D-1(3). We carry the obtained results to the 3-dimensional Minkowski space E-1(3) by means of the E. Study's dual line coordinates.
