Bosonic formulas for affine branching functions

Research output: Contribution to journalArticlepeer-review

Abstract

In this paper, we derive two bosonic (alternating sign) formulas for branching functions of affine Kac-Moody Lie algebras g . Both formulas are expressed in terms of the Weyl group and string functions of g.
