In this talk I will introduce the conformal bootstrap framework. I will first discuss how it can be useful to constrain CFT data and then I will present how it can be applied to find analytic solutions to crossing equations. If time permits, I will discuss an application to the case of superconformal field theories.

In the language of statistical physics, an extremal black hole is a zero temperature system with a huge amount of residual entropy. Understanding which class of counting formulas can account for a large degeneracy will undoubtedly unveil interesting properties of quantum gravity. In this talk I will discuss the application of Siegel modular forms to black hole entropy counting. The role of the Ig

What does it mean for a partial differential equation (PDE) or system of PDEs to be integrable? Is there a way to measure how “nonintegrable” a model might be? We shall discuss four results in fluid dynamics and gravitation aimed at answering these questions. Our discussion will reveal rich interconnections between nonlinear waves, astrophysics, combinatorics, geometric analysis, and algebr

We will start this talk with an introduction to the Atiyah-Segal approach to topological field theories. This will be a recollection from Ulrike Tillmann’s talk. We will then take a different direction and see how this approach led to developments of so-called higher algebra and higher categories in mathematics. We will see how a classification of so called "fully extended” topological field t

Based on the AdS/CFT correspondence, gauge/gravity duality provides a new relation between quantum field theories on flat space and gravity theories.
In addition to its intrinsic interest and its implications for the nature of gravity, this new duality provides a new approach to calculating observables in strongly coupled quantum field theories, for which there is no standard calculation method. W

Manifolds (and cobordisms) are at the very heart of topological quantum field theory (TQFT). We will survey how the study of TQFT from a topological point of view has led to a renaissance of manifold theory, and vice versa how a reinterpretation of classical manifold theory has led to deep insight in TQFT.

In this talk I will give a pedagogical introduction into perturbative algebraic quantum field theory (pAQFT) and briefly sketch the recent results. The pAQFT framework is a mathematically rigorous formalism that allows to prove structural results in quantum field theory (QFT). It combines the axiomatic framework of algebraic QFT with perturbative methods that involve for example expansion into Fey
