半欧几里得空间中的类时Bertrand曲线

Timelike Bertrand Curves in Semi-Euclidean Space

Soley Ersoy, Murat Tosun

摘要:

本文证明了在$\mathbb{E}_2^4$和$\mathbb{E}_ν^{n+1}$ $ ({n \ge 3})$中没有特殊的类时Frenet曲线是Bertrand曲线,从而Bertrand曲线的概念仅在$\mathbb{E}_1^2$和$\mathbb{E}_1^3$中是确定的.因此,在$\mathbb{E}_2^4$中定义了类时Bertrand曲线的一种推广,称为类时(1,3)-Bertrand曲线.此外,在$\mathbb{E}_2^4$中给出了类时(1,3)-Bertrand曲线的特征.

英文摘要:

In this paper, it is proved that, no special timelike Frenet curve is a Bertrand curve in $\mathbb{E}_2^4$ and also, in $\mathbb{E}_ν^{n+1}$ $ ({n \ge 3})$, such that the notion of Bertrand curve is definite only in $\mathbb{E}_1^2$ and $\mathbb{E}_1^3$. Therefore, a generalization of timelike Bertrand curve is defined and called as timelike (1,3)-Bertrand curve in $\mathbb{E}_2^4$. Moreover, the characterization of timelike (1,3)-Bertrand curve is given in $\mathbb{E}_2^4$.
