SUMMARY:Sebastián Barbieri Lemp (Universidad de Santiago de Chile): Self-s
 imulable groups
DESCRIPTION:Sebastián Barbieri Lemp: We say that a finitely generated grou
 p is self-simulable if every action on a zero-dimensional space which is e
 ffectively closed (this means it is "computable" in a specific way) is the
  topological factor of a subshift of finite type on said group. Even thoug
 h this seems like a property which is very hard to satisfy\, we will show 
 that these groups do exist and satisfy nice stability properties. We shall
  present several examples of these groups\, including a proof that Thompso
 n's group F satisfies the property if and only if it is non-amenable. Join
 t work with Mathieu Sablik and Ville Salo.\nhttps://arxiv.org/abs/2104.051
