Abstract:
We calculate the generators and commutation relations explicitly for higher symmetry algebras of a class of hyperbolic Lagrangian systems of Liouville type, in particular, for two-dimensional Toda chains associated with semisimple complex Lie algebras.
Keywords:
symmetry, two-dimensional Toda chain, Liouville-type system, Hamiltonian hierarchy, bracket.
