Fatma GökÇelik, İsmail Gök, F. Nejat Ekmekci, Yusuf Yayli

摘要:

本文根据平行运输标架引入了一种斜曲线。另外,我们在中定义了一个称为倾斜曲线的达布向量场的向量场,并给出了一个新的刻画,如:“α:\subset R \rightarrow E_4是倾斜曲线\Leftrightarrow k_1 \int k_1ds + k_2 \int \k_2 +k_3ds = 0”,其中k_1,k_2,K_3是曲线平行输运标架下的主曲率函数,并给出了类似的刻画,如“α:E_3是广义螺旋线\subset k_1 \int k_1ds + k_2 \int k_2ds = 0”其中k_1、k_2是曲线α的根据Bishop标架的主曲率函数。此外,我们举例说明,并绘制了他们的数字与Mathematica程序。

英文摘要:

In this paper, we introduce an inclined curves according to parallel transport frame. Also, we define a vector field called Darboux vector field of an inclined curve in and we give a new characterization such as: "α: I \subset R \rightarrow E^4 is an inclined curve \Leftrightarrow k_1 \int k_1ds + k_2 \int \k_2 +k_3ds = 0" where k_1, k_2, K_3 are the principal curvature functions according to parallel transport frame of the curve and we give the similar characterizations such as "α: I \subset R \rightarrow E^3 is a generalized helix \Leftrightarrow k_1 \int k_1ds + k_2 \int k_2ds = 0" where k_1, k_2 are the principal curvature functions according to Bishop frame of the curve α. Moreover, we illustrate some examples and draw their figures with Mathematica Programme.
