Abstract

The study aims to introduce some geometric properties of dual Cartan numbers. Since a unit timelike Cartan number with lightlike vector part corresponds to a parabolic rotation around a lightlike axis, it has been shown that the unit dual Cartan number with lightlike dual vector also corresponds to a parabolic rotation and a translation transformation in the Cartan frame. Also, the angle between the directed pseudo-null lines that tangent the same parabola is defined. Thus, the rotation and translation relationship between two directed pseudo-null lines is obtained. Also, the E. Study transformation is given for the directed pseudo-null lines.
