Abstract: I will explain how to characterise the distribution of some formally-defined random fields, by expressing their k-point functions in term of some functionals of Brownian paths. I will present the sort of ideas involved by considering Gaussian cases, but some more interesting examples will be quickly presented at the end (namely the case of phi4 and abelian Yang-Mills-Higgs in 2 dimensions).
