DESCRIPTION:Maxime Gheysens (Dresden)\nThe order topology on the first unc
 ountable ordinal yields a fascinating topological space\, well known for f
 eaturing "pathological" phenomena (such as sequential compactness without 
 compactness\, or a Stone–Čech compactification reduced to Alexandrov's 
 one-point compactification). In this talk\, we introduce its homeomorphism
  group\, which also comes with its own niceties. For instance\, it is an a
 menable topological group which is strongly allergic to any idea of distan
 ce: all its continuous isometric actions have bounded orbits and all its c
 ontinuous morphisms to metrisable groups are trivial.
