Null Bertrand Curves on Surfaces and their Darboux Frames in Minkowski Space-Time

H. S. Abdel Aziz, M.Khalifa Saad


In this paper, we investigated relationships among Darboux frames of the null Bertrand curves with space-like and time-like Bertrand partner curves which lie on a surface in the three-dimensional Minkowski 3-space. Moreover, it is shown that the null Bertrand curve is a null geodesic curve.
