Some results in geometry of hypersurfaces
OKAYASU Introduction.In this paper we get several theorems about hypersurfaces in space forms.In section 1, we show that if x : M n -*E n+1 is an isometric immersion of an n-dimensional complete non-compact Riemannian manifold whose sectional curvatures are greater than or equal to 0, then x(M) is unbounded …
