The Picard group of the universal abelian variety and the Franchetta conjecture for abelian varieties

Roberto Fringuelli, Roberto Pirisi

We compute the Picard group of the universal abelian variety over the moduli stack $A_{g, n}$ of principally polarized abelian varieties over $C$ with a symplectic…

The Picard group of the universal moduli space of vector bundles on stable curves

Roberto Fringuelli

We construct the moduli stack of properly balanced vector bundles on semistable curves and we determine explicitly its Picard group. As a consequence, we obtain an explicit descrip…
