Quantum equivalence of constrained WZNW and Toda theories

Primary tabs

O'Raifeartaigh, L. Ruelle, Philippe [UCL] Tsutsui, I.

It is shown that the equivalence between constrained Wess-Zumino-Novikov-Witten theories and generalized Toda theories established previously at the classical level is valid also at the quantum level. The point is that the WZNW→Toda reduction of the lagrangian is paralleled by a similar reduction of the path-integral measure.
