Linear Hyperelliptic Hodge Integrals

Algebraic Geometry 2019-10-17 v1

Abstract

We provide a closed form expression for linear Hodge integrals on the hyperelliptic locus. Specifically, we find a succinct combinatorial formula for all intersection numbers on the hyperelliptic locus with one λ\lambda-class, and powers of a ψ\psi-class pulled back along the branch map. This is achieved by using Atiyah-Bott localization on a stack of stable maps into the orbifold [P1/Z2][\mathbb{P}^1/\mathbb{Z}_2].
