Web(Third Chern-Lashof Theorem) T (M) = 2 precisely if M is a convex hypersurface in an (n+1)-dimensional linear subspace of RN. In the introduction to their first paper on total curvature, [CL57], Chern and Lashof cite the theorems of Fenchel and F´ary-Milnor, in [Fe29] and [F´a49, Mi50], as motivation for their results. WebJul 13, 2012 · We prove Gauß-Bonnet-type and Chern-Lashof-type formulas for immersions in hyperbolic space. Moreover we investigate the notion of tightness with respect to horospheres introduced by T.E. Cecil and P.J. Ryan. We introduce the notions of top-set and drop-set, and we prove fundamental properties of horo-tightness in …
