In this article,we prove that any complete finite index hypersurface in the hyperbolic space H4(-1)(H5(-1))with constant mean curvature H satisfying H 2>6463(H~2>175148respectively)must be compact. Specially,we verify that any complete and stable hypersurface in the hyperbolic space H~4(-1)(resp. H~5(-1))with constant mean curvature H satisfying H~2>6463(resp. H2>175148)must be compact. It shows that there is no manifold ...
