Cantor Minimal Systems
Share this pageIan F. Putnam
Within the subject of topological dynamics,
there has been considerable recent interest in systems where the
underlying topological space is a Cantor set. Such systems have an
inherently combinatorial nature, and seminal ideas of Anatoly Vershik
allowed for a combinatorial model, called the Bratteli-Vershik model,
for such systems with no non-trivial closed invariant subsets. This
model led to a construction of an ordered abelian group which is an
algebraic invariant of the system providing a complete classification
of such systems up to orbit equivalence.
The goal of this book is to give a statement of this classification
result and to develop ideas and techniques leading to it. Rather than
being a comprehensive treatment of the area, this book is aimed at
students and researchers trying to learn about some surprising
connections between dynamics and algebra. The only background material
needed is a basic course in group theory and a basic course in general
topology.
