A Rigidity Theorem for Hypersurfaces in Higher Dimensional Space Forms

Abstract

The classical Cohn-Vossen theorem states that two isometric compact convex surfaces in ${\mathbb{R}}^3$ are congruent. In this short note, we generalize the classical Cohn-Vossen Theorem to higher dimensional surfaces in space form $N^{n+1}(K)$ for $n\ge 2$.
