Abstract
For a smooth projective variety , we construct a Cartier divisor supported on the incidence locus in . There is a natural definition of the corresponding line bundle on a product of Hilbert schemes, and we show this bundle descends to the Chow varieties. This answers a question posed by Mazur.
