Abstract
We consider a curve alpha = alpha(s) in Minkowski 3-space E-1(3) and denote by {T,N,B} the Frenet frame of alpha. We say that alpha is a slant helix if there exists a fixed direction U of E-1(3) such that the function < N(s),U > is constant. In this work we give characterizations of slant helices in terms of the curvature and torsion of alpha. Finally, we discuss the tangent and binomial indicatrices of slant curves, proving that they are helices in E-1(3).
