摘要：

We obtain a resolution of (generically irreducible) highest-weight modules for coset conformal field theories G/H in terms of free field Fock spaces, by projection of the free field resolutions of G. We apply the resolution to calculate the characters of some G/H models, including the G-parafermions and G X G/G models. In this way we obtain, for example, explicit expressions for all Kac-Peterson string functions.
