Abstract
Given an immersed submanifold , we characterize the vanishing of the normal curvature at a point in terms of the behaviour of the asymptotic directions and the curvature locus at . We relate the affine properties of codimension 2 submanifolds with flat normal bundle with the conformal properties of hypersurfaces in Euclidean space. We also characterize the semiumbilical, hypespherical and conformally flat submanifolds of codimension 2 in terms of their curvature loci.
