RésumeInvariant point processes on groups are a rich class of p.m.p. actions. In fact, every essentially free p.m.p. action of a nondiscrete lcsc group is isomorphic to a point process. In this talk I will introduce point processes specifically for nonprobabilists, define their cost, and show that every essentially free point process on a group of the form G x Z has cost one. Joint work with Miklós Abért. La séance sera sur bigbluebutton, mais diffusée en salle 2015, RV sur https://bigbluebutton3.imj-prg.fr/b/fra-j6k-9fw
