Abstract:
The subject of the talk will be vertex-transitive infinite
connected graphs with bounded degree and with a property of large scale
simple connectedness. The most classical examples of such objects are
Cayley graphs of finitely presented groups, but I will explain that
there are (uncountably) many other, and I will study some topological
questions on the space of all such graphs. In particular I will give some answers to a question of Benjamini and Georgakopoulos asking which Cayley graphs are isolated. Based on
joint works with Romain Tessera.
