本文给出了孤立超曲面奇点的矩阵分解类MF (W)的显式循环极小A∞模型。关键的观察是使用Kontsevich的变形量化技术。在此基础上,我们利用Tsygan形式映射得到了MF (W)的半无限Hodge结构的范畴变异与原始形式理论中Saito的原始几何构造同构的比较定理。
In this paper, we present an explicit cyclic minimal A∞ model for the category of matrix factorizations MF (W) of an isolated hypersurface singularity. The key observation is to use Kontsevich's deformation quantization technique. Pushing this idea further, we use the Tsygan formality map to obtain a comparison theorem that the categorical Variation of Semi-infinite Hodge Structure of MF (W) is isomorphic to Saito's original geometric construction in primitive form theory.
