SLANT HELICES IN DUAL LORENTZIAN SPACE D3 1

Abstract

In this paper, we consider a unit speed dual Lorentzian curve a in dual Lorentzian space D31 and denote by {T ,N, B } the dual Frenet frame of a. We say that a is a slant helix if there exists a non-zero dual constant vector eld U in D 3 1 such that the dual function is a dual constant. Moreover, we give some characterizations of slant helice in terms of their dual curvatures. Finally, we show that dual tangent indicatrices and dual binormal indicatrices of slant helices are dual helices.
