The book also seems to be free from the typos and mathematical errors that plague more modern books. Although dated, this work is often cited and I needed a copy to track down some results.
The authors prove an equivalent definition of dimension, by showing that a space has dimension less than or equal to n if every point in the space can be separated by a closed set of dimension less than or equal to n-1 from any closed set not containing the point.

The author motivates the idea of an essential mapping quite nicely, viewing them as mappings that cover a point so well that the point remains covered under small perturbations of the mapping. Along the way, some concepts from algebraic topology, such as homotopy and simplices, are introduced, but the exposition is self-contained.
Years later, this was my inspiration for writing my own book about the many different ways to think about the nature of Computation. Comments 0 Please log in or register to comment. In chapter 2, the authors concern themselves with spaces having dimension 0. Would you like to tell us about a lower price? December Copyright year: That book, called “Computation: For these spaces, the particular choice of definition, also known as “small inductive dimension” and labeled d1 in the Appendix, is shown to be equivalent to that of the large inductive dimension d2Lebesgue covering dimension d3and the infimum of Hausdorff dimension over all spaces homeomorphic to a given space Hausdorff dimension not being intrinsically topologicalas well as to numerous other characterizations that could also conceivably be used to define “dimension.
English Choose a language for shopping. Almost every citation of this book in the topological literature is for this theorem. The final and largest chapter is concerned with connections between homology theory and dimension, in particular, Hopf’s Extension Theorem. Prices are subject to change without notice.

These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. Chapter 7 could be added as well if measure theory were also covered such as in a course in analysis. Some prior knowledge of measure theory is assumed here. Therefore we would like to draw your attention to our House Rules. Differential Geometry of Curves and Surfaces: Learn more about Amazon Prime.
The author also proves a result of Alexandroff on the approximation of compact spaces by polytopes, and a consequent definition of dimension in terms of polytopes. Amazon Renewed Refurbished products with a warranty. A successful theory of dimension would have to show that ordinary Euclidean n-space has dimension n, in terms of the inductive definition of dimension given.
Hausdorff wallmman is of enormous importance today due to the interest in fractal geometry. It would be advisable to just skim through most of this chapter and then just read the final 2 sections, or just skip it entirely since it is not that closely related to the rest of the results in this book. It is shown, as expected intuitively, that a 0-dimensional space is totally disconnected.
Page 1 of 1 Start over Page 1 of 1. The proof of this involves showing that the mappings of the n-sphere to itself which have different degree cannot be homotopic. User Account Log in Register Help. As these were very new ideas at the time, the chapter is very brief – only about 6 pages – and the concept of a non-integral dimension, so important to modern chaos theory, is only mentioned in passing.
This book includes the state of the art of topological dimension theory up to the year more or lessbut this doesn’t mean that it’s a totally dimensioon book.

The authors show this in Chapter 4, with the proof boiling down to showing that the dimension of Euclidean n-space is greater than or equal to n.

A respectful treatment of one another is important to us. If you want to become an expert in this topic you must read Hurewicz. Alexa Actionable Analytics for the Web. Originally published in As an undergraduate senior, I took a course in dimension theory that used this book Although first published inthe teacher explained that even though the book was “old”, that everyone who has learned dimension theory learned it from this book. These considerations motivate the concept of a universal n-dimensional space, into which every space of dimension less than or equal to n can be topologically imbedded.
If you read the most recent treatises on the subject you will find no signifficant difference on the exposition of the basic theory, and besides, this book contains a lot of interesting digressions and historical data not seen in more modern books.
Only in Chapter 7 is any work left to the reader, and there are no exercises.
Please find details to our shipping fees here. This allows a characterization of dimension in terms of the extensions of mappings into spheres, namely that a space has dimension less than or equal to n if and only if for every closed set and mapping from this closed set into the n-sphere, there is an extension of this mapping to the whole space.
