Title:Bi-invariant metrics on groups and topological complexity of diffeomorphisms
Seminar:Geometry Luncheon Seminar
Speaker:Sergei Ivanov, Steklov Institute
I will present a number of elementary formulated and highly intriguing problems that can be summarized as follows: which groups admit nontrivial bi-invariant metrics (or, equivalently, conjugation-invariant norms) on them? This question makes sense in a variety of contexts, from finitely generated groups to groups of diffeomorphisms. In the latter case, the question boils down to the study of a particular "complexity" norm of a diffeomorphism.
