关于两曲面交线的不变量
ON INVARIANTS OF THE INTERSECTION OF SURFACES
摘要
Abstract
We investigate invariants of the intersection of submanifolds of R3. We obtain an analogue of Euler formula by using the method of moving frames. The torsion of the intersection curve of two surfaces in R3 can be expressed by geodesic torsions,normal curvatures and the angle between surfaces.关键词
