Un graphe transitif est dit Local-Global rigide s’il existe tel que tout autre graphe dont les boules de rayon sont isométriques aux boules de rayon de est revêtu par . Un exemple de tel graphe est donné par l’immeuble de Bruhat–Tits de lorsque et est un corps local non-Archimédien de caractéristique nulle. Dans cet article nous étendons cette propriété de rigidité à une classe de graphes quasi-isométriques à l’immeuble, incluant les réseaux sans torsion de .
La démonstration est l’occasion de prouver un résultat sur la structure locale des immeubles. Nous montrons que si l’on fixe une -orbite dans l’immeuble, alors un sommet est uniquement déterminé par les sommets voisins contenus dans cette orbite.
A vertex-transitive graph is called Local-to-Global rigid if there exists such that every other graph whose balls of radius are isometric to the balls of radius in is covered by . An example of such a graph is given by the Bruhat–Tits building of with and a non-Archimedean local field of characteristic zero. In this paper we extend this rigidity property to a class of graphs quasi-isometric to the building including torsion-free lattices of .
The proof is the opportunity to prove a result on the local structure of the building. We show that if we fix a -orbit in it, then a vertex is uniquely determined by the neighbouring vertices in this orbit.
