A Landau-Ginzburg mirror theorem via matrix factorizations
arXiv:2001.00536
Abstract
For an in invertible quasihomogeneous singularity we prove an all-genus mirror theorem establishing an isomorphism between two cohomological field theories. On the -side it is the Saito-Givental theory given by a certain choice of a primitive form. On the -side, it is the reduced matrix factorization CohFT for the dual singularity with the maximal diagonal symmetry group.
