|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.|
