摘要：
The recently proposed all orders beta function for current interactions in two dimensions is further investigated. By using a strong-weak coupling duality of the beta function, and some added topology of the space of couplings we are able to extend the Bows to arbitrarily large or small scales. Using a nontrivial RG invariant we are able to identify sine-Gordon, sinh-Gordon and Kosterlitz-Thouless phases. We also find an additional phase with cyclic or roaming RG trajectories.
