If you have a question about this talk, please contact Christopher Brookes. In this talk I will summarise recent developments in the structure theory of infinite permutation groups. In particular I will present a recent result which describes the structure of all subdegree-finite primitive permutation groups. This class of groups includes, for example, all automorphism groups of locally finite primitive graphs. I will also discuss two consequences of this result. The first concerns topological groups that are totally disconnected and locally compact and the second is a structural description of those profinite groups that can be embedded into a topological group as a maximal open subgroup.
