Coinvariants for Lattice VOAs and q-Supernomial Coefficients
arXiv:math/0107003 · doi:10.1007/s00220-002-0690-7
Abstract
We propose an alternative definition of q-supernomial coefficients as characters of coinvariants for one dimensional lattice vertex operator algebras. This gives a new formula for q-supernomial coefficients. Along the way we prove that the spaces of coinvariants form a bundle over the configuration space of complex points (the configuration space includes diagonals).
