Solitons, Tau-functions and Hamiltonian Reduction for Non-Abelian Conformal Affine Toda Theories

L. A. Ferreira, J. L. Miramontes, J. Sanchez Guillen

We consider the Hamiltonian reduction of the two-loop Wess-Zumino-Novikov-Witten model (WZNW) based on an untwisted affine Kac-Moody algebra $\cgh$. The resulting reduced models, c…
