由拉格朗日环面构造的局部镜像函子

Localized mirror functor constructed from a Lagrangian torus

Cheol-Hyun Cho, Hansol Hong, Siu-Cheong Lau

摘要:

在辛流形X中固定一个弱无障碍的拉格朗日环面,我们定义一个全纯函数W,称为Floer势。我们构造了一个从X的X范畴到W的矩阵分解范畴的标准A-无穷函子。它提供了一个统一的方法来构造矩阵分解的拉格朗日弗洛尔理论。该技术适用于复曲面Fano流形变换拉格朗日膜矩阵分解。利用这种方法,我们还得到了复射影空间的实轨迹的矩阵分解镜像的显式表达式。

英文摘要:

Fixing a weakly unobstructed Lagrangian torus in a symplectic manifold X, we define a holomorphic function W known as the Floer potential. We construct a canonical A-infinity functor from the Fukaya category of X to the category of matrix factorizations of W. It provides a unified way to construct matrix factorizations from Lagrangian Floer theory. The technique is applied to toric Fano manifolds to transform Lagrangian branes to matrix factorizations. Using the method, we also obtain an explicit expression of the matrix factorization mirror to the real locus of the complex projective space.
