Leírás

Abstract: It is a folklore result in combinatorics that every finite 2d-regular graph is a Schreier graph of the free group on d generators. I will present extensions of this fact to a graph limit setting, as well as some limitations. I also hope to provide some introduction to measured group theory in order to illustrate why such questions are interesting.
