We show that under a hamiltonian reduction procedure, which respects conformal invariance, we obtain a hierarchy of Toda type field theories, which contain as submodels the Toda molecule and periodic Toda lattice theories. We also discuss the classical r-matrix and integrability properties.372-380engArtigo10.1016/0370-2693(91)91171-QAcesso restrito2-s2.0-00000125298215976645016606
