# Andrejewski Tage 2022

## Quivers, Representation Theory and Physics

**Workshop at the University of Cologne**

**7–9 September 2022**

The aim of this workshop is to promote the interactions between the physics and mathematics communities. Theoretical physics and mathematics have long enjoyed a symbiotic relationship, with mathematical advances leading to new physical theories, and physical intuition leading to new mathematical theorems.

In recent years, applications of quivers and representation theory to various areas of theoretical physics has become a vibrant area of interdisciplinary research. The aim of the workshop is to break down the language barrier between the mathematics and physics communities, through two mini-courses and several research talks aimed at a mixed audience, with a focus on the applications of quivers and their representation theory to current questions in physics.

Organizers: Severin Barmeier (Cologne), Daniel Labardini-Fragoso (UNAM/Cologne), Peter Littelmann (Cologne), Lang Mou (Cambridge), Sibylle Schroll (Cologne/NTNU)
