Singular Non-Abelian Toda Theories
J. F. Gomes, F. E. Mendonça da Silveira, G. M. Sotkov +1
The algebraic conditions that specific gauged G/H-WZW model have to satisfy in order to give rise to Non-Abelian Toda models with singular metric with or without torsion are found.…
Classical and Quantum -algebras
J. F. Gomes, F. E. Mendonça da Silveira, G. M. Sotkov +1
The problem of the classification of the extensions of the Virasoro algebra is discussed. It is shown that all -reduced -current algebras belong to one of the…
Parafermionic Reductions of WZW Model
J. F. Gomes, G. M. Sotkov, A. H. Zimerman
We investigate a class of conformal Non-Abelian-Toda models representing a noncompact parafermionions (PF) interacting with a specific abelian Toda theories and havi…
Symmetries of Non-Abelian Toda Theories
J. F. Gomes, G. M. Sotkov, A. H. Zimerman
The classical and quantum algebras of a class of conformal NA-Toda models are studied. It is shown that the Poisson brackets algebra generated by certain chiral and ant…
