我们给出了一组递归关系,它完全确定了商轨道C^3/Z_3的所有等变Gromov-Witten不变量。我们将这些不变量解释为G-Hodge积分,并通过Atiyah-Bott局部化在射影线上的扭曲稳定映射到Gerbes的模空间上产生它们之间的关系。
We exhibit a set of recursive relations that completely determine all equivariant Gromov-Witten invariants of the quotient orbifold C^3/Z_3. We interpret such invariants as G-Hodge Integrals, and produce relations among them via Atiyah-Bott localization on moduli spaces of twisted stable maps to gerbes over the projective line.
