Streszczenie
We focus on Bratteli–Vershik models of general compact zero-dimensional systems with the action of a homeomorphism. An ordered Bratteli diagram is called decisive if the corresponding Vershik map prolongs in a unique way to a homeomorphism of the whole path space of the Bratteli diagram. We prove that a compact invertible zero-dimensional system has a decisive Bratteli–Vershik model if and only if either the set of aperiodic points is dense, or its closure misses one periodic orbit.
