Severi degrees via representation theory
Yaim Cooper -- IAS
Location: SERC 206
Date & time: Wednesday, 24 April 2019 at 2:00PM - 3:00PM
Abstract: The Severi degrees of P1 x 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 ExP1. We will also discuss operators for calculating descendants.
Joint with R. Pandharipande.
