Slant helices in dual Lorentzian Space

SLANT HELICES IN DUAL LORENTZIAN SPACE D3 1

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 <N;U> is a dual constant.Moreover, we give some characterizations of slant helice in terms of their dualcurvatures. Finally, we show that dual tangent indicatrices and dual binormalindicatrices of slant helices are dual helices.

Keywords:

Dual Lorentzian space; Dual Frenet equations; Dual slant helices; Dual curves,
