<h4>Presentation</h4> <div class="level4"> <p> Forgetting the group structure via Schreier graphs, invariant random subgroups in discrete groups can be regarded as random graphs satisfying an invariance property called <em>unimodularity</em>. In the continuous setting, one can translate IRSs in Lie groups into random Riemannian manifolds with an ad hoc invariance property, which makes sense beyond the locally symmetric setting. </p> </div> <h4>References</h4> <div class="level4"> <ul> <li class="level1"> Ian Biringer, Omer Tamuz, <em>Unimodularity of Invariant Random Subgroups</em>, Trans.
