This thesis deals with two kinds of statistical mechanics problems: percolation ongroups and directed models. In the first case, we realise the group under considerationas a geometric object (via the notion of Cayley graph) before breaking it apartrandomly. The study of this process reveals deep connections between the geometricproperties of a group and the behaviour of Bernoulli percolation on it. In the secondcase, we focus on models where up and down play different roles, which makes severalquestions less hard to tackle.Chapter 1 strengthens the Indistinguishability Theorem of Lyons-Schramm, whichstates that the infinite clusters yielded by a Bernoulli percolation on a Cayley graphalmost surely all look alike. The non-Triviality of this ...
