Artin groups and their isomorphism problem
Ponente: Giovanni Sartori (Heriot-Watt University)Fecha: miércoles 25 de marzo de 2026 - 10:30Lugar: Aula Gris 1, ICMAT
Resumen:
In this talk, I will introduce the isomorphism problem for Artin groups, as well as isomorphism invariants that can be read from the defining graph. In particular, I will give an algebraic characterisation of the girth of the defining graph, showing that it is an isomorphism invariant.
