Special Bertrand Curves in semi-Euclidean space E^4_2 and their Characterizations

In [14] Matsuda and Yorozu.explained that there is no special Bertrand curves in Eⁿ (n 3) and they new kind of Bertrand curves called (N, B2)type Bertrand curves Euclidean space. In this paper , by using the similar methods given by Matsuda and Yorozu [14], we obtain that bitorsion of the quaternionic curve is not equal to zero in semiEuclidean space E4^2. Obtain (N,B2) type quaternionic Bertrand curves by 2 means of the {κ, τ, (σ − εtεT εN κ)} functions of curve.
