NPC - Non-positive curvature group actions and cohomology

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.
