A solvable lattice model and related Rogers-Ramanujan type identities
The authors give a natural generalization of Baxter's hard hexagon model to three spin states. An exactly solvable lattice model is presented. In chapters 2 and 3 of the paper the free and spin densities respectively are calculated. Related Rogers-Ramanujan type identities, which play a key role in the derivation of the theta function expressions for the spin densities, are also studied.
