Abstract: In this paper, we derive two bosonic (alternating sign) formulas for branching functions of affine Kac–Moody Lie algebras $\mathfrak{g}$. Both formulas are expressed in terms of the Weyl group and string functions of $\mathfrak{g}$.
Keywords: Kac–Moody algebra, branching function, BGG-resolution.
