关于零次椭圆轨道Gromov-Witten不变量

On degree zero elliptic orbifold Gromov-Witten invariants

Hsian-Hua Tseng

摘要:

我们用两种方法计算了亏格为一的具有非堆叠插入的零次轨道Gromov-Witten不变量,这是子方程和因子方程的例外情况。一种方法涉及相关模空间的详细分析。另一种方法是虚拟定位法,它适用于具有孤立不动点的环面作用。这些计算验证了这些不变量的几何评价。还计算了一些亏格为1的扭曲轨道Gromov-Witten不变量。

英文摘要:

We compute, by two methods, the genus one degree zero orbifold Gromov-Witten invariants with non-stacky insertions which are exceptional cases of the dilaton and divisor equations. One method involves a detailed analysis of the relevant moduli spaces. The other method, valid in the presence of torus actions with isolated fixed points, is virtual localization. These computations verify the conjectural evaluations of these invariants. Some genus one twisted orbifold Gromov-Witten invariants are also computed.
