Veronese minimizes normal curvatures

Differential Geometry 2025-03-18 v2

Abstract

Suppose M is a closed submanifold in a Euclidean ball of sufficiently large dimension. We give an optimal bound on the normal curvatures, guaranteeing that M is a sphere. The border cases consist of Veronese embeddings of the four projective planes.
