SUMMARY:Sine-Gordon model revisited (again) - Remi Rhodes (Aix-Marseille U

DESCRIPTION:In this talk\, I will discuss the Sine-Gordon model and its re
 lation with the 2D neutral Coulomb gas. This is a model of electric charge
 s with positive/negative signs interacting through the Coulomb potential. 
  In the case when particles are confined to the boundary of a 2D domain (c
 alled boundary Sine-Gordon model) I will present a short proof that allows
  us to completely solve the ultraviolet renormalization of this model\, in
 cluding correlation functions. The method is purely probabilistic and reli
 es on concentration methods for martingales.
