On a Residue Representation of Deformation, Koszul and Chiral Rings
P. Berglund, T. Hubsch
Abstract
A residue-theoretic representation is given for massless matter fields in (quotients) of (weighted) \ complete intersection models and the corresponding chiral operators in s. The well known polynomial deformations are thus generalized and the universal but somewhat abstract Koszul computations acquire a concrete realization and a general but more heuristic reinterpretation. A direct correspondence with a BRST-type analysis of constrained systems also emerges naturally.
