We compute the relative orbifold Gromov–Witten invariants of with respect to vertical fibers. Via a vanishing property of the Hurwitz–Hodge bundle, 2-point rubber invariants are calculated explicitly using Pixton’s formula for the double ramification cycle, and the orbifold quantum Riemann–Roch. As a result parallel to its crepant resolution counterpart for , the GW/DT/Hilb/Sym correspondence is established for . The computation also implies the crepant resolution conjecture for the relative orbifold Gromov–Witten theory of .

我们计算的相对轨道 Gromov-Witten 不变量相对于垂直纤维。通过 Hurwitz-Hodge 束的消失特性,使用 Pixton 的双分支循环公式和轨道量子 Riemann-Roch 明确计算 2 点橡胶不变量。因此,与它的 crepant 分辨率对应物平行, GW/DT/Hilb/Sym 对应建立为. 该计算还暗示了相对轨道 Gromov-Witten 理论的 crepant 分辨率猜想.
