Ponente: Macarena Arenas (University of Cambridge)

Fecha: Jueves, 4 de abril de 2024 - 11:30

Lugar: Aula Naranja, ICMAT

Resumen:

In its classical form, the Cohen-Lyndon property encodes independence between the relators in a group presentation. It is an interesting structural property that has been proven to hold, in one form or another, for various classes of groups. In this talk I will tell you a little bit about how this property arises naturally in connection with asphericity, and I will discuss some examples.
