摘要
In this paper, we derive the Bishop frames of the pseudo null curve and show that its normal Bishop vectors N-1 and N-2 can be obtained by applying the hyperbolic rotation and the composition of three rotations about two lightlike and one spacelike axis to the Frenet vectors N and B respectively. We also derive Bishop frame of the null Cartan curve and show that among all null Cartan curves in E-1(3) only the null Cartan cubic has two Bishop frames, one of which coincides with its Cartan frame. As an application, we obtain some solutions of the Da Rios vortex filament equation in terms of the Bishop frames of the pseudo null curves and null Cartan cubic. (C) 2018 Elsevier Inc.
