Isometric Immersions of Closed Manifolds of Nonnegative Curvature

Let M be a closed manifold and let be an immersion inducing a C²-smooth (respectively, polyhedral) metric of nonnegative curvature on M. If this nonnegativity property is preserved under all affine transformations of , then f is an embedding into the boundary of a C²-smooth convex body (respectively, a convex polyhedron) in a certain .
