Chiral rings of vertex algebras of mirror symmetry
arXiv:math/0209301
Abstract
We calculate chiral rings of the N=2 vertex algebras constructed from the combinatorial data of toric mirror symmetry and show that they coincide with the description of stringy cohomology conjectured previously in a joint work with A. Mavlyutov.
