Spacelike Bertrand curves in Minkowski 3-space revisited

In the geometry of curves in E , if the principal normal vector field of a given space curve with non-zero curvatures is the principal normal vector field of another space curve , then the curve is called a Bertrand curve and is called Bertrand partner of . These curves have been studied in di erent space over a long period of time and found wide application in di erent areas. Therefore, we have a great knowledge of geometric properties of these curves. In this paper, revested results for spacelike Bertrand curves with non-null normal vectors will be given with the previous studies on Bertrand curves in E . Follow this revested results, the Bertrand curve conditions of a spacelike curve are obtained in E . In addition, new curve samples that meet the obtained conditions are constructed and the graphs of these curves are given.
