Tau-functions and Dressing Transformations for Zero-Curvature Affine Integrable Equations
L. A. Ferreira, J. L. Miramontes, J. Sanchez Guillen
The solutions of a large class of hierarchies of zero-curvature equations that includes Toda and KdV type hierarchies are investigated. All these hierarchies are constructed from a…
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…
Comments on Two-Loop Kac-Moody Algebras
L. A. Ferreira, J. F. Gomes, A. Schwimmer +1
It is shown that the two-loop Kac-Moody algebra is equivalent to a two variable loop algebra and a decoupled - system. Similarly WZNW and CSW models having as algebraic struc…
