四维Minkowski空间内类空曲线的光锥高斯映射
摘要
定义了四维M inkow sk i空间内类空曲线的光锥高斯映射、光锥高度函数的概念
建立了这些对象的奇点与在洛仑兹群作用下曲线的几何不变量之间的关系.
Abstract
In this paper
we defined the notions of lightcone Gauss map and lightcone height function of a spacelike curve in Minkowski 4-space
and established the relationships between singularities of these objects and geometric invariants of curves under the action Lorentz group.
