Invariant random subgroups of strictly diagonal limits of finite symmetric groups
We classify the ergodic invariant random subgroups of strictly diagonal
limits of finite symmetric groups
Approximations of standard equivalence relations and Bernoulli percolation at p\_u
The goal of this note is to announce certain results in orbit equivalence
theory, especially concerning the approximation of p.m.p. standard equivalence
relations by increasing sequence of sub-relations, with applications to the
behavior of the Bernoulli percolation on graphs at the threshold pu. R\'esum\'e
