DESCRIPTION:Title: <a href="https://researchseminars.org/talk/DSSUJ/13/">M
 ultiorder of countable groups</a>\nby Tomasz Downarowicz as part of Dynami
 cal systems seminar at the Jagiellonian University\n\nLecture held in 1016
 .\n\nAbstract\nI will present the notion of a Multiorder of a countable gr
 oup\,\na particular case of an Invariant Random Order introduced by\nJohn 
 Kieffer in 1975.\nI will discuss how multiorder is related to orbit equiva
 lence to\nZ-actions and I will prove that if the group is amenable then\ne
 ach multiorder has the F\\o lner property. If time permits\, I will\nalso 
 show how to construct a uniformly F\\o lner multiorder of\nentropy zero\, 
 using a tiling system.\n
