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.
