Abstract:
We establish a weight-preserving bijection between the index sets of the spectral data of row-to-row and corner transfer matrices for Uqsl(n)undefinedU_q\widehat{sl(n)} restricted interaction round a face (IRF) models. The evaluation of momenta by adding Takahashi integers in the spin chain language is shown to directly correspond to the computation of the energy of a path on the weight lattice in the two-dimensional model. As a consequence we derive fermionic forms of polynomial analogues of branching functions for the cosets (A (1)n1)1(A (1)n1)1(A (1)n1){(A~{(1)}_{n-1})_{\ell -1}\otimes (A~{(1)}_{n-1})_{1}} \over (A~{(1)}_{n-1})_{\ell}, and establish a bosonic-fermionic polynomial identity.
