Mini-Workshop: Renormalisation and Randomness

Abstract

In recent decades, renormalisation, which has long been a workman’s tool for theoretical physicists, has also become an essential mathematical tool that appears in many guises. Within mathematics, renormalisation bridges across topics such as combinatorics and stochastic analysis. Yet, in part due to a lack of a common language, the advances on the mathematical side do not seem to fully reach out to the theoretical physicist. Conversely, the mathematician rarely benefits from the physicist’s expertise in renormalisation. The goal of this workshop is to bridge this gap and provide a platform for communication and exchange of ideas, a first step in the direction of increased interaction and cross fertilisation between the two communities.
