Counterexamples in Topology (Dover Books on Mathematics) Kindle Edition
Price | New from | Used from |
According to the authors of this highly useful compendium, focusing on examples is an extremely effective method of involving undergraduate mathematics students in actual research. It is only as a result of pursuing the details of each example that students experience a significant increment in topological understanding. With that in mind, Professors Steen and Seebach have assembled 143 examples in this book, providing innumerable concrete illustrations of definitions, theorems, and general methods of proof. Far from presenting all relevant examples, however, the book instead provides a fruitful context in which to ask new questions and seek new answers.
Ranging from the familiar to the obscure, the examples are preceded by a succinct exposition of general topology and basic terminology and theory. Each example is treated as a whole, with a highly geometric exposition that helps readers comprehend the material. Over 25 Venn diagrams and reference charts summarize the properties of the examples and allow students to scan quickly for examples with prescribed properties. In addition, discussions of general methods of constructing and changing examples acquaint readers with the art of constructing counterexamples. The authors have included an extensive collection of problems and exercises, all correlated with various examples, and a bibliography of 140 sources, tracing each uncommon example to its origin.
This revised and expanded second edition will be especially useful as a course supplement and reference work for students of general topology. Moreover, it gives the instructor the flexibility to design his own course while providing students with a wealth of historically and mathematically significant examples. 1978 edition.

Also, several Venn diagrams and reference charts (including a general reference chart) help find quickly any kind of counterexample and illustrate which implications are true or false.
Some examples are also illustrated for better comprehension, usually when describing weird neighborhoods.
I purchased this paperback edition (I don't know if there is a hardcover one), and it arrived on time and in mint condition. The book is well printed and well edited, easy to use and read.


Das Buch besteht aus 2 Teilen: Einem Beispielteil, in dem zahlreiche topologische Räume aufgeführt sind, von denen jeweils einige wichtige Eigenschaften oder nicht-Eigenschaften bewiesen werden, und einem Tabellenteil, in dem die Beispiele sowie zahlreiche topologische Eigenschaften aufgeführt sind, so dass man ablesen kann ob Raum A die Eigenschaften X, Y und Z hat. Benutzt habe ich das Buch meist folgendermaßen: Ich wollte wissen, ob X und Y zusammen Z implizieren. Dazu suchte ich in der Tabelle nach einem Gegenbeispiel, also einem Raum der die Eigenschaften X und Y, aber nicht Z hat. Da meine Intuition in der Topologie schlecht funktioniert, wurde ich oft fündig und konnte mir so viel Zeit, die ich sonst mit suchen in Lehrbüchern, Foren oder eigenen Beweis/Gegenbeispielversuchen verbracht hätte, ersparen.
Es sollte allerdings jedem klar sein dass es sich hier um ein Nachschlagewerk, und kein Lehrbuch, handelt. Eine kompakte Einführung in die Begrifflichkeit wird zwar gegeben, ist aber eher als Referenz und zum Nachschlagen zu gebrauchen denn als Einführung.
Einziges, kleines Manko: In den Tabellen verrutsche ich manchmal in der Zeile oder Spalte, da sie wirklich sehr umfangreich und teilweise zweiseitig sind. 2 Geodreiecke schaffen hier notfalls Abhilfe.
