Title: Phi 4 via random currents
Abstract: The phi 4 model is a simple candidate for a nontrivial euclidean field theory.
From the point of view of statistical mechanics, however, it (rigorously or otherwise)
exhibits a wide range of beautiful phenomena.
I will survey some upcoming joint works with collaborators towards understanding some
global probabilistic properties of this model, and highlight some irresistible conjectures.
I hope to at least explain a probabilistic representation of correlations via a type of random current representation.
