Some New Integrable Models in Field Theory and Statistical Mechanics

  • Héctor de Vega
Part of the NATO Advanced Study Institutes Series book series (volume 82)


The triangular relations [l–3] (also called factorization equations or Yang-Baxter equations)
are the clue of the resolution of two-dimensional interable models in quantum field theory and statistical mechanics[3,4,5]. In (1) the indices run from one to N, S kl ij are N4 functions (in general complex) of the variable O. The physical interpretation of the S kl ij depends on the context where they are considered.
