Description
Quantum groups and graph theory may seem like distant areas, yet intriguing connections emerge when they intersect. After an introduction to the notion of quantum automorphism groups of finite graphs, we will focus on 0-hyperbolic graphs and a computation of their quantum automorphism group. If time permits, we will also show how their quantum symmetries can be fully understood through their classical properties, due to their structural constraints. This talk is based on joint work with Amaury Freslon and Paul Meunier.
