亏格为1的实Gromov-Witten不变量的注记

Notes on genus one real Gromov-Witten invariants

Mohammad Farajzadeh Tehrani

摘要:

本文对具有实a结构的辛流形,包括Calabi-Yau三重流形,定义了亏格为1的实Gromov-Witten不变量,并利用等变局部化方法计算了射影空间的亏格为1的实不变量.对于这个定义,我们将对应于辛环面上三种可能的对合类型的三个模空间,通过沿公共边界粘合它们,得到一个无余维1边界的模空间,然后研究全空间的定向。模一个技术几何引理,我们可以证明该结果是相应的实辛流形的不变量。在前面提到的例子中,我们的主要动机是表明,物理学家对存在独立的环,莫比乌斯和克莱因瓶不变量的期望可能并不总是正确的。

英文摘要:

In this paper, we propose a definition of genus one real Gromov-Witten invariants for certain symplectic manifolds with real a structure, including Calabi-Yau threefolds, and use equivariant localization to calculate certain genus one real invariants of the projective space. For this definition, we combine three moduli spaces corresponding to three possible types of involutions on a symplectic torus, by gluing them along common boundaries, to get a moduli space without codimension-one boundary and then study orientation of the total space. Modulo a technical conjectural lemma, we can prove that the result is an invariant of the corresponding real symplectic manifold. In the aforementioned example, our main motivation is to show that the physicists expectation for the existence of separate Annulus, Mobius, and Klein bottle invariants may not always be true.
