Abstract:
-matrices associated to the vector representations of the quantum groups for the classical Lie algebras are constructed. For the and algebras the complete -matrix is found by an application of the bootstrap equations. It is shown that the simplest form for the -matrix which generalizes that of the Gross-Neveu model is not consistent for the non-simply-laced algebras due to the existence of unexplained singularities on the physical strip. However, a form which generalizes the -matrix of the principal chiral model is shown to be consistent.- quantum group: representation
- Yang-Baxter equation: solution
