常挠率球面曲线的一个显式公式

An Explicit Formula for the Spherical Curves with Constant Torsion

Demetre Kazaras, Ivan Sterling

摘要:

本文给出了单位双球面$S^2(1)$中所有常挠曲线$τ$的显式表达式。这些曲线和它们的基本性质自19世纪90年代以来就已为人所知,附录中讨论了其中的一些性质。图\ref{peter}中显示了使用标准ODE软件包计算的$τ=.1,.5,1,2$曲线示例。虽然它们的存在性和一些一般性质是已知的,但我们用超几何函数给出的它们的显式公式是新的。

英文摘要:

The purpose of this article is to give an explicit formula for all curves of constant torsion $τ$ in the unit two-sphere $S^2(1)$. These curves and their basic properties have been known since the 1890's, and some of these properties are discussed in the Appendix. Some example curves, computed with a standard ODE package, with $τ=.1,.5,1,2$ are shown in Figure \ref{peter}. Though their existence and some of their general properties were known, our explicit formulas for them, in terms of hypergeometric functions, are new.
