Moduli spaces for group actions on the line
Ponente: Joaquim Brum (Universidad de la República Uruguay)Fecha: miércoles 10 de diciembre de 2025 - 16:30Lugar: Aula Naranja, ICMAT
Resumen:
In this talk, I will discuss the moduli space of actions of a finitely generated group G on the real line. I will first explain what we mean by this space, and then describe its structure in the cases of solvable and Thompson-like groups. Finally, if time permits, I will present some open problems concerning the structure of these spaces for amenable groups.
This is a joint work with Nicolás Matte Bon, Michele Triestino and Cristóbal Rivas.
