Timelike spherical curves according to equiform Bishop framein 3-dimensional Minkowski space

In this paper, we study the equiform Bishop formulae for the equiform timelike curves in3-dimensional Minkowski space where the equiform timelikespherical curves are defined accord-ing to the equiform Bishop frame. We establish a necessary and sufficient condition for an equiformtimelike curve to be an equiform timelike spherical curve. Furthermore, we give certain character-izations of equiform spherical curves in 3-dimensional Minkowski space, which are timelike withan equiform spacelike principal normal vector.
