双参数Calabi-Yau超曲面的矩阵分解、Massey积和F-项

Matrix Factorizations, Massey Products and F-Terms for Two-Parameter Calabi-Yau Hypersurfaces

Johanna Knapp, Emanuel Scheidegger

摘要:

利用矩阵分解的语言讨论了双参数Calabi-Yau超曲面镜像中的B型张量积膜。我们确定了膜在Gepner点的开弦模。通过同时启用体积模量和边界模量,我们可以使膜变形远离Gepner点。使用矩阵分解的变形理论,我们计算Massey产品。这些包含有关高阶变形和障碍物的信息。障碍物被编码在F项方程中,我们从Massey乘积算法获得。我们表明,F-项可以整合到一个有效的超势。我们的研究结果提供了一个成分,这些超曲面的开/闭镜像对称。

英文摘要:

We discuss B-type tensor product branes in mirrors of two-parameter Calabi-Yau hypersurfaces, using the language of matrix factorizations. We determine the open string moduli of the branes at the Gepner point. By turning on both bulk and boundary moduli we then deform the brane away from the Gepner point. Using the deformation theory of matrix factorizations we compute Massey products. These contain the information about higher order deformations and obstructions. The obstructions are encoded in the F-term equations, which we obtain from the Massey product algorithm. We show that the F-terms can be integrated to an effective superpotential. Our results provide an ingredient for open/closed mirror symmetry for these hypersurfaces.
