Abstract:I will present new examples of algebraic cohomology classes on smooth projective complex varieties that are not integral linear combinations of classes of smooth subvarieties. Some of these examples have dimension 6, the lowest possible. More precisely, I will consider the case of minimal cohomology classes on Jacobians of very general curves. This is joint work with Olivier Debarre.
