Computations of Gromov-Witten invariants of toric varieties

Algebraic Geometry 2025-02-07 v3

Abstract

We present the Julia package ToricAtiyahBott.jl, providing an easy way to perform the Atiyah-Bott formula on the moduli space of genus 00 stable maps M0,m(X,β)\overline{M}_{0,m}(X,\beta) where XX is any smooth projective toric variety, and β\beta is any effective 11-cycle. The list of the supported cohomological cycles contains the most common ones, and it is extensible. We provide a detailed explanation of the algorithm together with many examples and applications. The toric variety XX, as well as the cohomology class β\beta, must be defined using the package Oscar.jl.
