Some characterizations of constant ratio curves according to Bishop frame in Minkowski 4-space

In this paper, we consider a curve in Minkowski 4-space E^4_1 as a curve whose position vector can be written as linear combination of its Bishop frame vectors. In particular, we study the non-null curves in E^4_1 and characterize such curves in terms of their Bishop curvatures. Further, we obtain some results of T-constant type and N-constant type curves according to their Bishop curvatures E^4_1. .
