Singularity Properties of Timelike Sweeping Surface in Minkowski 3-Space

Singularity Properties of Timelike Sweeping Surface in Minkowski 3-Space

In this paper, we give the parametric equation of the Bishop frame for a timelike sweeping surface with a unit speed timelike curve in Minkowski 3-space. We introduce a new geometric invariant to explain the geometric properties and local singularities of this timelike surface. We derive the suffici...
