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.
Readership
Undergraduate and graduate students and researchers interested in dynamical systems.
Reviews & Endorsements
[This] book is a very nicely written introduction to the orbit equivalence theory of Cantor minimal systems. I highly recommend it for students who would like to conduct research in this area...The book gives the intuition needed to work in this area and the inspiration for further research. The style of writing is very encouraging and leaves a reader with an impression of being at the lecture and listening to the author.
