Abstract:

Local Lagrangeans are derived for a class of

SU(2)

invariant sigma models admitting two commuting Kac-Moody algebras at the level of Poisson brackets. The one loop renormalizability of these models is established. Some heuristic arguments are presented in favour of their quantum integrability.
