For a senior undergraduate or first year graduate-level course in Introduction to Topology. Appropriate for a one-semester course on both general and algebraic topology or separate courses treating each topic separately.

This text is designed to provide instructors with a convenient single text resource for bridging between general and algebraic topology courses. Two separate, distinct sections (one on general, point set topology, the other on algebraic topology) are each suitable for a one-semester course and are based around the same set of basic, core topics. Optional, independent topics and applications can be studied and developed in depth depending on course needs and preferences.
Hallmark features of this title
- Advanced topics such as metrization and imbedding theorems, function spaces, and dimension theory are covered after connectedness and compactness.
- Order of topics proceeds naturally from the familiar to the unfamiliar: Begins with the familiar set theory, moves on to a thorough and careful treatment of topological spaces, then explores connectedness and compactness (with their many ties to calculus and analysis), and then branches out to the new and different topics mentioned above.
- 1- or 2-semester coverage: Provides separate, distinct sections on general topology and algebraic topology. Each of the text's 2 parts is suitable for a one-semester course, giving instructors a convenient single text resource for bridging between the courses. The text can also be used where algebraic topology is studied only briefly at the end of a single-semester course.
- Many examples and figures: Exploits six basic counterexamples repeatedly and avoids overemphasis on “weird counterexamples.”
- Exercises are varied in difficulty from the routine to the challenging. Supplementary exercises at the end of several chapters explore additional topics.
- Deepens students' understanding of concepts and theorems just presented versus mere test comprehension. The supplementary exercises can be used by students as a foundation for an independent research project or paper.
New to this Edition
New and updated features of this title
- Greatly expanded, full-semester coverage of algebraic topology with extensive treatment of the fundamental group and covering spaces.
- What follows is a wealth of applications to the topology of the plane (including the Jordan curve theorem), to the classification of compact surfaces, and to the classification of covering spaces.
- A final chapter provides an application to group theory itself.
- This explores the subject much more extensively, with 1 semester devoted to general topology and a second to algebraic topology.
