We analyze the locus of singular sections of a very ample vector bundle on a smooth complex variety. We characterize when this projective subscheme is a hypersurface. In the hypersurface case, we also compute its degree.

Joint work with Hirotachi Abo (University of Idaho, USA) and Robert Lazarsfeld (Stony Brook University, USA).
