Die folgenden Informationen sind noch nicht freigegeben und deshalb unverbindlich: Amenability SemesterWiSe 2025 / 26 Lecturer Clara Löh/F. Hofmann/M. Wasmeier Type of course (Veranstaltungsart) Seminar German title Amenabilität Contents Amenability is a concept for groups, group actions or spaces that revolves around "almost-invariance". This concept can be characterised in many different settings and thus leads to rich interactions between group theory, geometry, dynamical systems, and functional analysis. For instance, (non-)amenability plays a key role in the Banach--Tarski paradox: One can decompose the 3-ball into finitely many pieces that can be reassambled into two disjoint copies of the 3-ball of the same size. 
In this seminar, we will study various descriptions of amenable groups and actions, as well as classial applications of amenability. In particular, we will start with basics on infinite groups.
