摘要：

We present fermionic quasi-particle sum representations for some of the characters (or branching functions) of (G(1))1 X (G(1))1/(G(1))2 for all simply-laced Lie algebras G. For given G the characters are written as the partition function of a set of rank G types of massless quasi-particles in certain charge sectors, with nontrivial lower bounds on the one-particle momenta. We discuss the non-uniqueness of the representation for the identity character of the critical Ising model, which arises in both the A1 and E8 cases.
