Characterizing Varieties Using Birational Transformations

Nathan Chen, Louis Esser, Andriy Regeta +2

Suppose is an irreducible complex variety. We show that when is ruled, the group of birational transformations , as a group, determines up to birational transfo…

Asymptotically rigid mapping class groups III: Presentations and isomorphisms

Anthony Genevois, Anne Lonjou, Christian Urech

This article is dedicated to the computation of an explicit presentation of some asymptotically rigid mapping class groups, namely the braided Higman-Thompson groups. To do so, we…

Representations of finite subgroups of Cremona groups

Alexander Duncan, Bailey Heath, Christian Urech

The Cremona group of rank n over a field k is the group of birational automorphisms of the n-dimensional projective space over the field k. We study the minimal dimension such that…
