DESCRIPTION:<span>Co-author: Dorothea Bahns		(University of Goettingen)   
      <br></span><br>In this talk I will present recent results on the conv
 ergence of the formal S-matrix and interacting currents in the Sine-Gordon
  model in 2 dimensions\, obtained directly in Minkowski signature\, using 
 a class of Hadamard states. In our approach one starts with a perturbation
  series obtained from the formalism of perturbative AQFT and then one can 
 prove the convergence of the series by some simple estimates. Our result o
 pens the posibility to use pAQFT methods to study integrable models in 2 d
 imensions and to construct local observables in such models.<br><br>Relate
