Stochastic Analysis meets QFT - Critical Theory
University of Münster, June 12-14, 2023
Supported by the ERC Grant "Global Estimates for Singular Stochastic PDEs" and the Cluster of Excellence Mathematics Münster
Organisers:
- Ajay Chandra (Imperial College)

- Raimar Wulkenhaar (Münster)
Over the last years, a number of new methods from stochastic analysis have been developed that allowed a new perspective on constructive field theory. Among these are the theory of singular stochastic PDEs, Barashkov-Gubinelli’s variational approach, and constructive approaches to Polchinski's continuous renormalisation group flow. While much progress has been made on controlling small scales for subcritical/superrenormalisable models there is much less known regarding the same question for critical/just-renormalizable models.
The constructive renormalisation programme has been successfully applied to quantum field theories of matrix models and tensor models. Matrix models tend to be asymptotically safe and tensor models asymptotically free at their critical dimension. These models are comparably simple and thus provide an ideal target to extend the above stochastic analysis methods to critical dimension.
The aim of this short workshop is to bring together some leading experts from both the stochastic analysis community and the QFT community to explore these exciting developments further.

Talks
Summer School on Wave Turbulence
MIT, Cambridge | July 24-28, 2023
Sponsored by the Simons Collaboration on Wave Turbulence
Four Hour Short Course By:
- Raffaele Ferrari (MIT)
- Isabelle Gallagher (Ecole Normale Supérieure)
- Jacques Vanneste (University of Edinburgh)
- Hendrik Weber (University of Münster)
- Miguel Escobedo (Universidad del País Vasco)
This summer school will introduce participants to several topics in partial differential equations at the intersection of mathematical analysis and physics through five lecture series, covering both theory and application. There are two main themes: kinetic equations describing large systems of interacting waves or particles and singular stochastic PDE. The target audience is graduate students and early-career researchers.
Application deadline: 15 May 2023
