Chow rings of the symmetric powers/Jacobian of a curve
Alexander Polishchuk, University of Oregon

Abstract: The main result described in the talk will be the isomorphism of the direct sum of the Chow rings of all symmetric powers of a curve, equipped with the Pontryagin product ring structure, and the ring of polynomials in two variables over the Chow ring of the Jacobian. I will also explain the connection to the study of tautological cycles on the Jacobian.
