[edit] Sample Applications
It would be nice with a couple of examples of applications. YohanN7 (talk) 18:48, 10 December 2007 (UTC)
I added a simple application although its formatted very badly, also some pictures of the commutative diagrams would be nice --LkNsngth (talk) 03:54, 24 March 2008 (UTC)
- eh, examples are nice, even better if they are somewhat interesting. that computation of π1(S^2) is a trivial one; both A and B are disks. maybe we can replace the e.g. Mct mht (talk) 04:08, 24 March 2008 (UTC)
- I added another calculation, the n fold torus, but its formatted quite badly so it would be great of someone better at this could make it more concise and more aesthetically pleasing. I also might have made a few errors so it would be great if someone could help proof read it. LkNsngth (talk) 04:43, 6 April 2008 (UTC)
- I tried to make it more aesthetically pleasing and got completely carried away. I want to say that your argument was correct. Orthografer (talk) 07:02, 6 April 2008 (UTC)
