On characters of irreducible highest weight modules of negative integer level over affine lie algebras
We prove a character formula for irreducible highest weight modules over a simple affine vertex algebra of level k, attached to a simple Lie algebra g, which are locally g-finite, in the cases when g is of type An and Cn (n≥2) and k = −1. We also conjecture a character formula for types D4, E6, E7,...
