摘要
本文考虑伪球面,H^4(-1)中具有两个相等常数主曲率 R 的完备超曲面,给出了当第三主曲率为常数时的分类;并且证明了:若 R>1,则 M 是全脐的或者是无脐点的.
The paper considers about complete hypersurface M in four dimensional unit pseudo-sphere H^4(—1)with two equal con- stant principal curvaturd R.The classification of M is given when the third principal curvature is a constant.It also shows that M is either totally umbilical or else umbilic free,if R>1.
