SUMMARY:Olena Karpel (Institute of Mathematics of the Polish Academy of Sci
 ences\, Warsaw\, Poland): Decisive Bratteli-Vershik models
DESCRIPTION:Olena Karpel: The goal of this talk is to determine when a home
 omorphism of a compact zero-dimensional metric space has a decisive Bratte
 li-Vershik representation. An ordered Bratteli diagram is called decisive 
 if the corresponding Vershik map prolongs in a unique way to a homeomorphi
 sm of the whole path space of a Bratteli diagram. We prove that a compact 
 invertible zero-dimensional system has a decisive Bratteli-Vershik model i
 f and only if the set of aperiodic points is dense\, or its closure misses
  one periodic orbit.\nThis is a joint work with T. Downarowicz.\nhttps://a
