On The B-Scrolls With Time-Like Directrix In 3-Dimensional Minkowski Space E³?

In this paper, as special ruled surfaces, b-scrolls with time-like directrix are introduced in 3-dimensional Minkowski space E-j3, [1] and [3]. The generating vector of b-scroll is space-like V3 binormal vector of time-like directrix curve. The Normal vector, the matrix corresponding to the shape operator, the Gaussian and mean curvatures, I. and II. Fundamental forms, asymptotic lines and curvature lines of b-scrolls together with striction space are studied.
