22. What Is Topology? An introductory essay by Neil Strickland, University of Sheffield.Category Science Math topology......What is topology? We can analyse the structure of Y using the methods of algebraictopology, and learn a number of interesting and nontrivial things about it. http://www.shef.ac.uk/~pm1nps/Wurble.html

What is topology? Topologists are mathematicians who study qualitative questions about geometrical structures. We do not ask: how big is it? but rather: does it have any holes in it? is it all connected together, or can it be separated into parts? A commonly cited example is the London Underground map. This will not reliably tell you how far it is from Kings Cross to Picadilly, or even the compass direction from one to the other; but it will tell you how the lines connect up between them. In other words, it gives topological rather than geometric information. Again, consider a doughnut and a teacup, both made of BluTack. We can take one of these and transform it into the other by stretching and squeezing, without tearing the BluTack or sticking together bits which were previously separate. It follows that there is no topological difference between the two objects. Consider the problem of building a fusion reactor which confines a plasma by a magnetic field. Imagine a closed surface surrounding the plasma. At each point on the surface, the component of the magnetic field parallel to the surface must be nonzero, or the plasma will leak out. We are thus led to the following question: given a surface S, is it possible for there to be a field of vectors tangent at each point of S which is nowhere zero? It turns out that this depends solely on the topological nature of S. If S is the surface of a sphere, it is not possible. Magnetic confinement of a ball of plasma just does not work. The only type of surface for which this approach is possible is the inner tube shape, which is of course the solution universally used for such reactors. (I do not claim that engineers needed topologists to point this out; on the contrary, this is a nice example precisely because many people can see for themselves that the claim is true.) Another amusing consequence of the same argument is that at any given time, some point on the Earth's surface is windless.

Two versions of the conference logo are presented above. The logo depicts the many facets of the conference and their interconnections. Each develops in its own direction while maintaining strong connections with the core and being connected with other subject areas. The logo is itself a topological object, with the lines forming the interconnections depicting knot 5 . This logo also depicts a five-pointed star, which is appropriate for this being the third of this series of conferences in a four-year period to be held in the Lone Star State of Texas, a state which has had a major influence on the development of topology.

Algebraic Topology To get an idea of what's in the book you can look at the Table of Contents and the Preface Printed Version . The book has been published by Cambridge University Press in a paperback edition (ISBN 0-521-79540-0) for US$30 and a hardback edition (ISBN 0-521-79160-X) at a considerably higher price. It is now in a third printing, with corrections of some minor errors in the earlier printings. (See farther down this page for a list of the corrections.) Electronic Version: By special arrangement with the publisher, an online version will continue to be available for download here. Individuals may print out single copies for their own use, but xeroxing multiple copies is not allowed. There are several different formats available. First of all, you can download the whole book as a single rather large pdf file (3.5Meg) of about 550 pages. If you wish to save paper when you print it out, there is also a pdf doublepage version with two pages side by side, reduced in size so that they fit on one sheet of standard US size paper, and probably also on European size paper. Another option is to download the individual chapters separately. These are available in both pdf and postscript formats. The postscript files are compressed as zip files, but they are still quite a bit larger than the pdf files. To get enough material for a one-semester introductory course you could start by downloading just Chapters 0, 1, and 2, along with the Table of Contents, Bibliography and Index. Here are the individual parts:
