DESCRIPTION:2D continuum Gaussian free field (GFF) is a canonical model fo
r random surfaces. It has various nice properties like conformal invarianc
e or the Markov property\, but also a notable disadvantage when thought of
as a surface - it is merely a random generalized function that cannot be
defined pointwise. Nevertheless\, when one is stubborn enough and insists
on studying its geometry\, beautiful things start to appear: for example\,
connections to SLE processes of Schramm or to Brownian loop soups. I woul
d like to give a short overview of some of the results obtained in this di
rection in collaboration with T. Lupu\, E. Powell\, A. Sepulveda and W. We
rner. In particular\, I would like to explain how to decompose the 2D cont
inuum GFF into an independent sum of measures.\n\nhttps://indico.math.cnrs
