Let e P p nร‚n , f P p nร‚t , where F is an arbitrary ยฎeld. We describe the possible characteristic polynomials of e f, when some of its rows are prescribed and the other rows vary. The characteristic polynomial of e f is deยฎned as the largest determinantal divisor (or the product of the invariant fac
