DESCRIPTION:Percolation models have been playing a fundamental
  role in statistical physics for several decades b
 y now. They had initially been investigated in the
  gelation of polymers during the 1940s by chemistr
 y Nobel laureate Flory and Stockmayer. From a math
 ematical point of view\, the birth of percolation 
 theory was the introduction of Bernoulli percolati
 on by Broadbent and Hammersley in 1957\, motivated
  by research on gas masks for coal miners. One of 
 the key features of this model is the inherent sto
 chastic independence which simplifies its investig
 ation\, and which has lead to deep mathematical re
 sults. During recent years\, the investigation of 
 the more realistic and at the same time more compl
 ex situation of percolation models with long-range
  correlations has attracted significant attention.
 \n\nWe will exhibit some recent progress for the G
 aussian free field with a particular focus on the 
 understanding of the critical parameters in the as
 sociated percolation models. What is more\, we als
 o survey recent progress in the understanding of t
 he model at criticality via its critical exponents
  as well as the universality in the local geometry
  of the underlying graph.\n\nThis talk is based on
  joint works with A. Prevost (U Cambridge) and P.-
 F. Rodriguez (Imperial College).
