By Anne Parreau
Appears in collection : Metric Graph Theory and Related Topics / Théorie métrique des graphes et interactions
I will present an overview and some specific problems concerning appearances of weakly modular graphs in group theory, and particularly, in geometric group theory. It will be based on works joint with Victor Chepoi and other colleagues from metric graph theory.
