Time: June 8th 2022, 14:00-15:00 CET Speaker: Trishen Gunaratnam (University of Geneva) 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.
