在这封信中,我们提出了一般型射影超曲面的量子上同调环上的广义镜面变换的另一个表征。该特性对于明确确定广义镜像变换的形式很有用。作为一个应用,我们将广义镜像变换重新推导到我们之前论文中获得的 d=3 有理 Gromov-Witten 不变量,并在超曲面的第一个 Chern 类等于 -H(即 k-N=1)的情况下明确确定 d=4,5 有理 Gromov-Witten 不变量的广义镜像变换。
In this letter, we propose another characterization of the generalized mirror transformation on the quantum cohomology rings of general type projective hypersurfaces. This characteristic is useful for explicit determination of the form of the generalized mirror transformation. As an application, we rederive the generalized mirror transformation up to d=3 rational Gromov–Witten invariants obtained in our previous paper, and determine explicitly the generalized mirror transformation for the d=4,5 rational Gromov–Witten invariants in the case when the first Chern class of the hypersurface equals -H (i.e. k-N=1).
