The first part of this book is a text for graduate courses in topology.
In chapters 1 - 5, part of the basic material of plane topology, combinatorial
topology, dimension theory and ANR theory is presented. For a student who
will go on in geometric or algebraic topology this material is a prerequisite
for later work. Chapter 6 is an introduction to infinite dimensional topology;
it uses for the most part geometric methods, and gets to spectacular results
fairly quickly. The second part of this book, chapters 7 & 8, is part
of geometric topology and is meant for the more advanced mathematician
interested in manifolds. The text is self-contained for readers with a
modest knowledge of general topology and linear algebra; the necessary
background material is collected in chapter 1, or developed as needed.
One can look upon this book as a complete and self-contained proof of Torunczyk's
Hilbert cube manifold characterization theorem: a compact ANR X is a manifold
modeled on the Hilbert cube if and only if X satisfies the disjoint-cells
property. In the process of proving this result several interesting and
useful detours are made.
