Groups acting on quasi-median graphs. An introduction

Genevois, Anthony

Séminaire de théorie spectrale et géométrie, Tome 35 (2017-2019), pp. 43-68.

Quasi-median graphs have been introduced by Mulder in 1980 as a generalisation of median graphs, known in geometric group theory to naturally coincide with the class of CAT(0) cube complexes. In his PhD thesis, the author showed that quasi-median graphs may be useful to study groups as well. In the present paper, we propose a gentle introduction to the theory of groups acting on quasi-median graphs.
