SUMMARY:Maximum and coupling of the sine-Gordon field - Michael Hofstetter

DESCRIPTION:In recent years the extremal behaviour of log-correlated spati
 al Gaussian processes has drawn a lot of attention. For the lattice discre
 te Gaussian free field (DGFF) in d=2 as well as for general log-correlated
  Gaussian fields\, the limiting law of the centred maximum has been identi
 fied as a randomly shifted Gumbel distribution.\n\nIn this talk I will exp
 lain how an analogous result is obtained for the non-Gaussian sine-Gordon 
 field. I will present a strong coupling at all scales of the sine-Gordon f
 ield with the Gaussian free field and demonstrate how this can be used to 
 extend existing methods for the maximum of the DGFF. The talk is based on 
 a joint work with R. Bauerschmidt.
