DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GiG2024/6/">
 Boomerang subgroups</a>\nby Waltraud Lederle (Dresden University of Techno
 logy) as part of Groups in Galway 2024\n\nLecture held in McMunn lecture t
 heatre.\n\nAbstract\nGiven a locally compact group\, its set of closed sub
 groups can be endowed with a compact\, Hausdorff topology. With this topol
 ogy\, it is called the Chabauty space of the group. Every group acts on it
 s Chabauty space via conjugation. This action has connections to rigidity 
 theory\, Margulis' normal subgroup theorem and measure preserving actions 
 of the group via so-called Invariant Random Subgroups (IRS).\nI will give 
 a gentle introduction into Chabauty spaces and IRS and state a few classic
 al results. I will define boomerang subgroups and explain how special case
 s of the classical results can be proven via them.\nBased on joint work wi
 th Yair Glasner.\n
