摘要：

The duality symmetries of WZW and coset models are discussed. The exact underlying symmetry responsible for semiclassical duality is identified with the symmetry under affine Weyl transformations. This identification unifies the treatment of duality symmetries and shows that in the compact and unitary case they are ''act symmetries of string theory to all orders in alpha' and in the string coupling constant. Non-compact WZW models and cosets are also discussed. A toy model is analyzed suggesting that duality can survive as an exact symmetry.
