Title:  Severi degrees via representation theory

Abstract:   The Severi degrees of ℙ1×ℙ1 can be computed in terms of an
explicit operator on the Fock space F[ℙ1]. We will discuss this and
variations on this theme. We will explain how to use this approach to
compute the relative Gromov-Witten theory of other surfaces, such as
Hirzebruch surfaces and E×ℙ1. We will also discuss operators for
calculating descendants. Joint with R. Pandharipande.
