We show that a compact Riemannian-manifoldwith strictly convex simply connected boundary and sectional curvatureis isometric to a convex domain in a complete simply connected space of constant curvature, provided thaton planes tangent to the boundary of. This yields a characterization of strictly convex surfaces with minimal total curvature in Cartan-Hadamard-manifolds, and extends some rigidity results of Greene-Wu, Gromov, and Schroeder-Strake. Our proof is based on a recent comparison formula for total curvature of Riemannian hypersurfaces, which also yields some dual results for. References
