From Am Trigonometric S-Matrices to the Thermodynamic Bethe Ansatz
Abstract
The thermodynamic Bethe Ansatz equations that have been proposed to describe massive integrable deformations of the coset conformal field theories gk× gl/gk+l are shown to result directly by applying the usual thermodynamic Bethe Ansatz arguments to the trigonometric S-matrices for the algebras g=am-1.
