Abelian Varieties not Isogenous to Jacobians over global fields
Ananth Shankar, Department of Mathematics, University of Wisconsin, Madison,

We prove that over an arbitrary global field, for every g > 3 there exists an abelian variety of dimension g, which is not isogenous to a Jacobian. We will also discuss this question over finite fields. This is joint work with Jacob Tsimerman.
