In recent years, the development of analytic tools to study geometric questions in metric spaces beyond Riemannian manifolds has seen tremendous progress and led to many structural results which shed a new light even on classical questions. The goal of this HIM program is to further refine such tools and explore their applications, like the study of filling invariants, norms, volumes, energies, in various concrete geometric frameworks. The program aims at bringing together researchers in analysis on metric spaces, geometric group theory, differential geometry, higher Teichmüller theory and low dimensional topology to isolate and enhance common core ideas and tie these strands to a more global theory, geared at making progress towards some well established open problems. The trimester will include an Introductory Winter School "Analysis and geometry on groups and spaces" (January, 27-31), the Felix Klein Lectures (tba), and an International Conference "Differential geometry beyond Riemannian manifolds” (March, 24-28). The online application platform to participate in this trimester program will be accessible from January 19 to June 30, 2024 under https://him-application.uni-bonn.de/index.php?id=5701 For applications of PhD students and postdocs, a letter of recommendation is required. Please make sure this letter is sent before July 1, 2024 to application-metric-analysis@him.uni-bonn.de In case of questions concerning services and administration, please contact events@hcm.uni-bonn.de
Future
Quantum field theories (QFTs) have been successfully applied, throughout the last 70 years, to model and analyze diverse physical phenomena; in particular, critical behavior in statistical mechanics, and interactions of fundamental particles. However, a rigorous mathematical framework to construct and understand these theories is still limited. This program will further pursue this direction, building on recent developments towards QFT coming from random geometry and probability theory. In particular, the goal is to bring together researchers with different viewpoints and expertise on this multifaceted topic. With this combined expertise, the program aims at addressing some of the main challenges and key open questions in the field, including in the following areas: advances in quantum gauge theories in 3D and 4D rigorous constructions of exactly solvable quantum field theories, especially in 2D more generally, analysis of probabilistic aspects of quantum field theories the theory of phase transitions, in particular for systems with continuous symmetry, and related phenomena
