四维欧氏空间球面曲线的一个几何性质
A geometric property of spherical curves in 4-dimensional Euclidean space
摘要
Abstract
Investigated the geometric properties of spherical curves by using of Frenet formula in 4-dimensional Euclidean space and obtained a necessary and sufficient condition in judging that space curves are spherical curves.关键词
