Organisers:
Bringing together a small group of leading young experts in their respective research areas, the goal of the workshop is to stimulate collaboration and exchange between participants. The event will provide specialists' points of view on recent developments in stochastic analysis, with a particular focus on singular stochastic PDEs. The workshop is exclusively aimed at postdocs in stochastic analysis, as well as PhD students at the University of Münster.

This is the third and final workshop of the Bernoulli Center Program "New developments and challenges in Stochastic Partial Differential Equations”. Stochastic partial differential equations (SPDEs) model a wide range of systems that involve space-time varying randomness. Due to their far reaching scope, SPDEs appear naturally in numerous scientific domains, including physics, biology, and finance. Since its initial development and thanks to recent impressive advances, the field has become mature with many different specialities and sub-fields, and bridging the gap between these sub-fields is often demanding. The role of the workshop and the research program is to bring researchers together to facilitate communications and exchange of fundamental ideas.

Stochastic partial differential equations arise naturally in several models of random phoenomena, in such fields as biology, physics and engineering. In particular, while deterministic models represent an efficient tool to describe time-evolution of real-world systems, they fail in rendering the presence of possible microscopic uncertainty of the model. Such randomness components may be related to several factors and are usually tracked through the introduction of a stochastic source of randomness in the equations involved. One of the most challenging goal of the mathematics of stochastic partial differential equations is the understanding of quantitative and qualitative properties of solutions and their dependence on the coefficients.
The aim of the workshop is to bring together leading experts, as well as a number of talented young researchers and to share fresh information on new results and future perspectives. The stay at the Institute will promote informal interaction progress in collaborations.

Organisers:
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.

Four Hour Short Course By:
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
