In this book, which may be used as a self-contained text for a beginning
course, Professor Lefschetz aims to give the reader a concrete working
knowledge of the central concepts of modern combinatorial topology:
complexes, homology groups, mappings in spheres, homotopy,
transformations and their fixed points, manifolds and duality theorems.
Each chapter ends with a group of problems.
Originally published in 1949.
