Talk:Grothendieck group

I quickly turned the equations into TeX, but obviously, this page needs to be improved. Here are some suggestions. The page is supposed to be about the Grothendieck group of an additive category. If it remains as such, the notion of "exact sequence" used in the definition needs to be clarified. Another option (in my opinion better) is to change the subtitle of this page to "of an exact category", and then to consider various exact structures on an additive category. --Baptiste Calmes 21:57, 16 April 2012 (CEST)

I have modified the subtitle as you proposed and also modified the beginning of the article according to Talk:EoM:This_project#Preferred_style. Some MR/ZBL entries and MSC were also added. Remark: Very often, in the references the letter K from "K-theory" is encoded by a png file, which should be removed as well. --Ulf Rehmann 22:59, 16 April 2012 (CEST)
