Abstract

We classify codimension two complex submanifolds of projective space Xn having the property that any line through a general point xX having contact to order two with X at x automatically has contact to order three. We give applications to the study of the Debarre-de Jong conjecture and of varieties whose Fano variety of lines has dimension 2n – 4.
