Matrix factorizations, minimal models and Massey products

摘要: We present a method to compute the full non–linear deformations of matrix factorizations for ADE minimal models. This is based on calculation higher products in cohomology, called Massey products. The algorithm yields polynomial ring whose vanishing relations encode obstructions D–branes characterized by these factorizations. coincides with critical locus effective superpotential which can be computed integrating relations. Our results are agreement those obtained from solving A–infinity point out relation superpotentials Kazama–Suzuki will illustrate our findings various examples, putting emphasis E6 model.
