SUMMARY:Infinite primitive permutation groups and embeddings of profinite 
 groups as open maximal subgroups - Simon Smith (LIncoln)

DESCRIPTION:In this talk I will summarise recent developments in the struc
 ture theory of infinite permutation groups. In particular I will present a
  recent result which describes the structure of all subdegree-finite primi
 tive permutation groups. This class of groups includes\, for example\, all
  automorphism groups of locally finite primitive graphs.\n\nI will also di
 scuss two consequences of this result. The first concerns topological grou
 ps 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.
