R2^4中一类常曲率的伪迷向曲线

Pseudo Rull Curves with Constant Curvature in Semi-Euclidean Space

Petrovic-Torgasev M.等[1]对半欧氏空间中常曲率的伪迷向曲线进行了分类。但是分类中并没有包含k1=1,k3=±1的常曲率伪迷向曲线。这类曲线在文中被确定,修正了他们的分类定理。

Petrovic -Torgasev M. , Ilarslan K. and Nesovic E. have classified pseudo null curves with constant curvatures in semi - Euclidean space R2^4 . But the pseudo null curves with constant curvatures k1 = 1 ,k3 = ± 1 are not included in the classification theorem. In the present paper these curves are confirmed and the new discovery has revised the original one.
