Talk:Karoubi envelope

Apparently the wording in the definition was confusing, which led User:MiNombreDeGuerra to change the wording incorrectly. I hope things are clarified now. Sam Staton 18:28, 12 June 2007 (UTC)

I believe that the definition of what it means for an idempotent to split is incorrect: It defines an idempotent as a map (A, e) -> (A', e')... it should just be (A, e). Can anyone confirm? Patrick S. (talk) 22:27, 25 October 2008 (UTC)
