局部对称空间的紧致超曲面

On the Compact Hypersurfaces in a Locally Symmetric Space

研究一类局部对称Ｒｉｅｍａｎｎ流形的紧致超曲面，得到了使浸入超曲面的第二基本形式模长的平方为常数的几个充分条件．

This poper dcals with the compact hypcrsurfaccs in a locally symmetric ffiemannian manifold. Some sufficient conditions arc obtained, under which the Square length of the second fundamental form of the immerse hypcrsurfaces is a constant.
