摘要 对于平面上的卵形域,本文发现其Ros亏格为单位速度外法向流下的几何不变量.进一步,对于欧氏空间R3中的卵形域,本文将给出一些新的单位速度外法向流下的几何不变量,这些几何不变量将包含平面上的结果. For plane ovaloid domain,it is found that Ros'deficit is an invariant of the unit-speed outward normal flow.Moreover,some new invariants of the unit-speed outward normal flow are given for ovaloid domain in R3,which are the generalizations of the invariants in R2.
