DESCRIPTION:Remi Rhodes (Aix-Marseille)\nI will discuss the Sine-Gordon mo
 del and its relation with neutrallog-gas. This is a model of electric char
 ges with positive/negative signs interacting through a\nlogarithmic potent
 ial (or Coulomb potential in 2D). In the case when particles are confined 
 to the boundary of a 2D domain (called boundary Sine-Gordon model) I will 
 present a short proof that allows us to completely solve the ultraviolet r
 enormalization of this model until the Berezinky-Kosterlitz-Thouless (BKT)
  transition\, including renormalization of correlationfunctions. The metho
 d is purely probabilistic and relies on concentration methods for martinga
 les.\nTime permitting\, I will then discuss the infrared problem and how i
 t relates to basic properties of imaginary Gaussian multiplicative chaos.\
 n\nTalk with a mini-break:  25-30 minutes "colloquium style"\, then a 15
  minutes coffee / cake / discussions break\, followed by 25-30 minutes of 
 more details.\n\n-- A Probability and Stochastic Analysis Seminar --
