Infinite Dimensional Symmetry in Topological-Holomorphic QFTs
Dr Joaquin Liniado
(Edinburgh)
Abstract
In recent years, lower-dimensional quantum field theories have often been understood as descending from higher-dimensional topological-holomorphic gauge theories, with their algebraic and geometric structures thereby becoming manifest. This perspective has led to substantial progress in the study of two-dimensional integrable field theories, four-dimensional integrable systems, and, more recently, celestial holography. In this talk, we present a new instance of this mechanism starting from a five-dimensional holomorphic BF theory. We show how it gives rise to a three-dimensional QFT, whose symmetries are naturally organized into a shifted Poisson vertex algebra. Such structures appear ubiquitously in holomorphic–topological twists of three-dimensional N=2 supersymmetric field theories. We conclude with some remarks on how this construction may be framed within the context of twisted holography.

A stochastic control approach to Euclidean field theories with exponential interaction
Michael Hofstetter
(University of Vienna)
Abstract
In this talk, I demonstrate how to obtain couplings of the Liouville field and the sinh-Gordon field with the Gaussian free field in dimension $d=2$, such that the difference is in a Sobolev space of regularity $\alpha > 1$. The analysis covers the entire L2 phase. The main tool is the variational approach to Euclidean field theories by Barashkov and Gubinelli applied to field theories with exponential interaction. The additional key ingredients are estimates for the short scales of the minimizer of the variational problem and several applications of the Brascamp-Lieb inequality.
