Group actions on contractible $2$ -complexes II

Kevin Ivan Piterman, Iván Sadofschi Costa

In this second part we prove that, if $G$ is one of the groups $PSL_{2} (q)$ with $q > 5$ and $q \equiv 5 (mod 24)$ or $q \equiv 13 (mod 24)$ , then the fundamental group of eve…

Group actions on contractible $2$ -complexes I

Iván Sadofschi Costa

In this series of two articles, we prove that every action of a finite group $G$ on a finite and contractible $2$ -complex has a fixed point. The proof goes by constructing a nontri…

Generalized small cancellation conditions, non-positive curvature and diagrammatic reducibility

Martin Axel Blufstein, Elias Gabriel Minian, Iván Sadofschi Costa

We present a metric condition $τ^{'}$ which describes the geometry of classical small cancellation groups and applies also to other known classes of groups such as two-dimensi…
