SU(2,R)(sub q) symmetries of non-Abelian Toda theories

摘要

The classical and quantum algebras of a class of conformal NA-Toda models are studied. It is shown that the SL (2,R)(sub q). Poisson brackets algebra generated by certain chiral and antichiral charges of the nonlocal currents and the global U(1) charge appears as an algebra of the symmetries of these models.
