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.
