FJRW-环与二维Landau-Ginzburg镜像对称

FJRW-Rings and Landau-Ginzburg Mirror Symmetry in Two Dimensions

Pedro Acosta

摘要:

对于任何非退化的拟齐次超曲面奇点W和一个允许的对角对称群G,Fan、Jarvis和Ruan构造了一个上同调域论,它是Landau-Ginzburg A模型背后的数学结构的候选者。当用奇点W的轨道Milnor环作为B-模型,用Fan,Jarvis和Ruan构造的Frobenius代数H_{W,G}作为A-模型时,得到如下猜想:对于拟齐次奇点W和W的对称群G,存在对偶奇点W^T,使得W/G的轨道A-模型同构于W^T的B-模型.我将证明这个猜想对二维可逆圈势$W$及其最大对角对称群$G_{W}$成立。

英文摘要:

For any non-degenerate, quasi-homogeneous hypersurface singularity W and an admissible group of diagonal symmetries G, Fan, Jarvis, and Ruan have constructed a cohomological field theory which is a candidate for the mathematical structure behind the Landau-Ginzburg A-model. When using the orbifold Milnor ring of a singularity W as a B-model, and the Frobenius algebra H_{W,G} constructed by Fan, Jarvis, and Ruan, as an A-model, the following conjecture is obtained: For a quasi-homogeneous singularity W and a group G of symmetries of W, there is a dual singularity W^T such that the orbifold A-model of W/G is isomorphic to the B-model of W^T. I will show that this conjecture holds for a two-dimensional invertible loop potential $W$ with its maximal group of diagonal symmetries $G_{W}$.
