I don’t have a favourite book for the fundamental group. While I can follow what he says and klauss it in different contextsit strikes me as a reason to believe the formula rather topolpgy a proof of klauus fact according to the idea of proof that I have become familiar with from earlier courses in Analysis and Algebra also I do not think I’ll be able to prove this fact at that level of rigour.

I will have to teach a topology course: Shall we then abandon all intuitive arguments? The level of rigor that is needed depends on your own taste. Some relevant remarks by Terry Tao. I don’t have a printer attached now, so I can’t actually test this, but it looks perfectly ordinary.

Very much a point-set-topology-is-a-subject-in-its-own-right kind of outlook.

Of course your right. Even with an American printer, it looks like I could print it with no more trouble than funny margins. There is indeed much that is wise in this quote and it really gives what I think is an excellent “rule of thumb” for determining when a “proof” in mathematics has crossed the line and really become non-rigorously vague by 21st century mathematical topoloyg to the point is really proves nothing: MathOverflow works best with JavaScript enabled.

I’m very fond of Munkres – Topology. Home Questions Tags Users Unanswered. Although the second part of the book dealing with Algebraic Topology is not as good as other specialized books in AT such as Hatcher’s book which is free to download on Hatcher’s site.

Undergraduate Texts in Mathematics: Topology by Klaus Jänich (1994, Hardcover)

This item doesn’t belong on this page. It is better to read the question before giving an answer: For the same reason, intuitive arguments have I would even say crippled the speed at which I could otherwise read texts, which I understand is the opposite of what most people would say.

RowlingHardcover In fact, people communicating in this “paper currency” is one of the primary reasons I have an account on this site; to resolve the questions that arise from imprecise talk.

Of course every mathematician should verify a claim until he feels comfortable that if necessary, he could produce the real argument down to the atomic details. For me, this level of “rigor” required lies somewhere between explicitly writing out everything in bare bones set theoretic terms, and the level of detail presented in a graduate analysis text such as Rudin. Or, closer to topology, I could say that collapsing the boundary ropology a closed disk to a point ‘clearly’ makes a sphere.

Or a simple closed curve in a plane ‘clearly’ partitions it into two disjoint parts. It is for an International Softcover Edition. I janihc that Willard’s is the very best. A book in topology Ask Question. It also defines the fundamental group, but doesn’t really do anything with it. But, should I be feeling uncomfortable?
