摘要：

It is shown that a compact spacelike hypersurface which is contained in the chronological future (or past) of an equator of de Sitter space is a totally umbilical round sphere if one of the mean curvatures H-l dues not vanish and the ratio H-k/H-l is constant for some k, l, 1 less than or equal to 1 < k <less than or equal to> n. This extends the previous result in [J. Geom. Phys. 31 (1999) 195, Theorem 7]. (C) 2001 Elsevier Science B.V. All rights reserved.
