Gerby局部化、Z_3-Hodge积分和C^3/Z_3的GW理论

Gerby Localization, Z_3-Hodge Integrals and the GW Theory of C^3/Z_3

Charles Cadman, Renzo Cavalieri

摘要:

我们给出了一组递归关系,它们完全确定了商轨道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局部化方法在射影直线上的扭曲稳定映射的模空间上建立它们之间的关系。

英文摘要:

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.
