Hi Terry (and others), You might have a look at my paper with Grunenfelder "Families Parametrized by Coalgebras", J. Alg. 107 (1987), 316-375, which gives a different perspective on the topic. Bob
Hi, I have heard that naive questions are allowed at the cat list, so here goes:
The diagonal map in spaces often gives a co-commutative diagonal map in homology, so I want to understand the special properties of the category of co-commutative coalgebras.
It seems to be a "well-known fact" that the category of co-commutative coalgebras over a field is a cartesian closed category, but I can't seem to find much discussion of the internal hom. Can you suggest any reference?
Thanks, Terry Bisson
