作为一个基本定理,我们证明了Minkowski空间中伪球面之间的四个Legendrian对偶。我们可以应用这种对偶来构造伪球面中类空超曲面的外微分几何。本文坚持光锥中的类空超曲面,建立了一种外赋微分几何,我们称之为光锥微分几何。
We show four Legendrian dualities between pseudo-spheres in Minkowski space as a basic theorem. We can apply such dualities for constructing extrinsic differential geometry of spacelike hypersurfaces in pseudo-spheres. In this paper we stick to spacelike hypersurfaces in the lightcone and establish an extrinsic differential geometry which we call the lightcone differential geometry.
