The content of this article appears to be included in differential graded coalgebra#cdgc. Should this article be deleted?
I think it should be kept, as it is useful to be able to point directly to cd-DGCAs. But of course there is lots of room to improve on this entry.
Re #2: Do you want to keep the 2008 terminology like “codifferential”? I don’t think this adjective is used in the literature. MathSciNet returns 33 matches for “differential coalgebra” and 0 matches for “codifferential coalgebra”. Google Ngram Viewer returns lots of matches for “differential coalgebra” and no matches for “codifferential coalgebra”.
I mean that we should have a page dedicated to co-commutative dg-coalgebras, in addition to a page on general dg-coalgebras, just as there is a page differential graded-commutative algebra in addition to differential graded algebra.
(Instead of debating this I should just write it, but I don’t have the leisure right now.)
Re #4: Yes, so I was asking what the new name of the article CoDGCA should be: graded-cocommutative differential coalgebra, or you really want “codifferential”?
Yes, “graded-cocommutative differential coalgebra” is the right term. (I don’t know which discussion you have in mind suggesting otherwise.)
(I don’t know which discussion you have in mind suggesting otherwise.)
I imagine this concerns the page title, adjusting the ’Co’ in CoDGCA.
I see. Yeah, there is lot’s of room to improve on this entry, starting with its title.
