| Abstract: | We give an algebro-geometric proof of some results of Morita concerning the pull back of a cohomology class in the Jacobian fibration of a family of curves to the family itself. We apply those to the question of ampleness of line bundles on the family of curves and its symmetric products. Received: 3 April 2001; in final form: 1 October 2001/ Published online: 4 April 2002 |
