Fundamental matrix factorization in the FJRW-theory revisited

Algebraic Geometry 2017-12-29 v1

Abstract

We present an improved construction of the fundamental matrix factorization in the FJRW-theory given in arXiv:1105.2903. The revised construction is coordinate-free and works for a possibly nonabelian finite group of symmetries. One of the new ingrediants is the category of dg-matrix factorizations over a dg-scheme.
