紧致超曲面上复曲面膜的镜像对称性

Mirror Symmetry for Toric Branes on Compact Hypersurfaces

M. Alim, M. Hecht, P. Mayr, A. Mertens

摘要:

本文利用环面几何研究了紧致Calabi-Yau流形上的开弦镜像对称。对于复曲面超曲面镜像对上的复曲面膜镜像对,我们得到了一个正则超几何微分方程组,其解决定了开/闭弦镜像映射和球面与圆盘的配分函数。我们定义了一个线性西格玛模型的膜几何形状和双复曲面多面体和复曲面膜几何形状之间的对应关系。该方法适用于研究的例子,在变形空间中的各个点的障碍和经典通畅膜模量。在开/闭变形空间上的平坦坐标系中计算大体积的瞬子膨胀,我们获得了枚举不变量的预测。

英文摘要:

We use toric geometry to study open string mirror symmetry on compact Calabi-Yau manifolds. For a mirror pair of toric branes on a mirror pair of toric hypersurfaces we derive a canonical hypergeometric system of differential equations, whose solutions determine the open/closed string mirror maps and the partition functions for spheres and discs. We define a linear sigma model for the brane geometry and describe a correspondence between dual toric polyhedra and toric brane geometries. The method is applied to study examples with obstructed and classically unobstructed brane moduli at various points in the deformation space. Computing the instanton expansion at large volume in the flat coordinates on the open/closed deformation space we obtain predictions for enumerative invariants.
