Abstract:
Benjamini, Schramm and Timar introduced the notion of
"separation profile" for a graph or finitely generated group. I will discuss a family of invariants that
generalise this idea, examples of the values obtained and applications to
non-embedding results.
Joint work with David Hume and Romain Tessera.
