# 3-Manifolds

Share this page
*John Hempel*

A careful and systematic development of the theory of the topology of 3-manifolds, focusing on the critical role of the fundamental group in determining the topological structure of a 3-manifold … self-contained … one can learn the subject from it … would be very appropriate as a text for an advanced graduate course or as a basis for a working seminar.

—Mathematical Reviews

For many years, John Hempel's book has been a standard text on the
topology of 3-manifolds. Even though the field has grown
tremendously, the book remains one of the best and most popular
introductions to the subject.

The theme of this book is the role of the fundamental group in
determining the topology of a given 3-manifold. The essential ideas
and techniques are covered in the first part of the book: Heegaard
splittings, connected sums, the loop and sphere theorems,
incompressible surfaces, free groups, and so on. Along the way, many
useful and insightful results are proved, usually in full
detail. Later chapters address more advanced topics, including
Waldhausen's theorem on a class of 3-manifolds that is completely
determined by its fundamental group. The book concludes with a list of
problems that were unsolved at the time of publication.

Hempel's book remains an ideal text to learn about the world of
3-manifolds. The prerequisites are few and are typical of a beginning
graduate student. Exercises occur throughout the text.
