# Ordered Groups and Topology

Share this page
*Adam Clay; Dale Rolfsen*

This book deals with the connections between
topology and ordered groups. It begins with a self-contained
introduction to orderable groups and from there explores the
interactions between orderability and objects in low-dimensional
topology, such as knot theory, braid groups, and 3-manifolds, as well
as groups of homeomorphisms and other topological structures. The
book also addresses recent applications of orderability in the studies
of codimension-one foliations and Heegaard-Floer homology. The use of
topological methods in proving algebraic results is another feature of
the book.

The book was written to serve both as a textbook for graduate
students, containing many exercises, and as a reference for
researchers in topology, algebra, and dynamical systems. A basic
background in group theory and topology is the only prerequisite for
the reader.

#### Reviews

Given the huge popularity enjoyed by low dimensional topology these days, and all for good reason, it should make a very positive impact. The book is easy to read and deals with very pretty mathematics.
