本文的第一部分是对Strominger-Yau-Zaslow猜想在不同背景下的研究进展进行综述。特别地,我们总结了给定一个由Kahler流形和一个反正则因子组成的对(X,D),X-D中的特殊Lagrange环面族和X中的全纯圆盘的加权计数如何被用来建立一个与X镜像的Landau-Ginzburg模型。在第二部分中,我们转向对具有全纯对合的Calabi-Yau流形和它们的对合的更投机的考虑。也就是说,给定一个表示Kahler流形X中的反正则类的两倍的超曲面H,我们试图将X-H上的特殊拉格朗日纤维化和X沿着H分支的(Calabi-Yau)双覆盖联系起来;不幸的是,镜像对称的含义还远不清楚。
The first part of this paper is a review of the Strominger-Yau-Zaslow conjecture in various settings. In particular, we summarize how, given a pair (X,D) consisting of a Kahler manifold and an anticanonical divisor, families of special Lagrangian tori in X-D and weighted counts of holomorphic discs in X can be used to build a Landau-Ginzburg model mirror to X. In the second part we turn to more speculative considerations about Calabi-Yau manifolds with holomorphic involutions and their quotients. Namely, given a hypersurface H representing twice the anticanonical class in a Kahler manifold X, we attempt to relate special Lagrangian fibrations on X-H and on the (Calabi-Yau) double cover of X branched along H; unfortunately, the implications for mirror symmetry are far from clear.
