Hugo Vanneuville (Lyon): Level set percolation for Gaussian fields

In this talk, we consider a random smooth Gaussian function from the
plane to \R and, given a level u, we colour the points where the
function is larger than u in black and the points where the function
is less than u in white. By relying on recent works by V. Beffara and
D. Gayet, we study the percolation properties of this random colouring
and try to compare it with Bernoulli percolation. Joint works with S.
Muirhead and A. Rivera.
