We will discuss a recent work of Christian Rosendal on coarse geometry of topological
groups. We will explore concepts such as the word metric, quasi-isometry, coarse
embedding for Polish groups. Typical examples of groups we will be interested in
are isometry groups of separable metric spaces, automorphism groups of countable
structures, Banach spaces with the addition operation or homeomorphism groups of
compact separable spaces. The seminar will be of interest to students in model theory,
geometric group theory, and functional analysis. The main reference will be the book
