The Geography of Amenable Subrelations of Acyclic Graphs and Beyond - Part II

Explore the intricate world of graph theory in this advanced lecture on the geography of amenable subrelations of acyclic graphs and beyond. Delivered by Anush Tserunyan from McGill University, Canada, at the Banach Center, this hour-long presentation delves into complex mathematical concepts. Begin with an introduction and example, then progress through topics such as hyperfiniteness, symbolic dynamics, and graphs of Sigma and X. Examine quasiinvariant measures, chosen ends, and generalized notions of topology on ends. Investigate the generalized atoms dichotomy and open questions in the field. Conclude with a comprehensive proof, gaining valuable insights into this specialized area of mathematics.
