This is a list of things to add/improve in no particular order. Some topics may have their own article, in which case, a pointer can be added with less information than otherwise would be called for.
Add a section on reduced homology
Mention the universal coefficient theorem somewhere appropriate
Add a table giving (Z-)homology of some common example spaces
n-sphere
n-torus
genus g surface
real/complex protective spaces
Add a properties section including:
Excision/Mayer-Vietoris
Homology of a disjoint union and of a wedge sum
Homology of a suspension
Künneth formula
Work in the fact that gives the number of path connected components
...?
Add a section on the homology of a point as an example
The way that the singular chain complex is presented needs to be cleaned up significantly

Why does singular cohomology link to this page, if cohomology is never mentioned? 3:58 PM CST 28 Dec 2004.
I think a table of common homology groups or a link to one (should someone know where one might be found)
would be very useful. Alexwright 19:57, 29 November 2006 (UTC)[reply]
What is Z_n in the section "Singular chain complex". It seems to be invoked without having ever been defined. Should it be C_n? Or do you mean the center of something?72.69.194.235 (talk) 21:15, 28 November 2009 (UTC)[reply]
May defines C_n to be on the nondegenerate singular simplices. Perhaps the article should mention alternative definitinos?165.124.97.20 (talk) 18:43, 16 May 2011 (UTC)[reply]
