    am starting model structure on dg-coalgebras.

    In the process I

    remembered that we already had differential graded coalgebra with pretty much complementar content and merged the two entries. Now dg-coalgebra is a redirect to the former.

    In the same vein, I have now finally merged the content at dg-algebra into the largely complementary content at differential graded algebra and made the former keyword redirect to the latter

    Added the statement of the two main results in Hinich's "formal stacks"-article to model structure on dg-coalgebras.

    Somebody sends the following by email, a question on one of the articles cited at model structure on dg-coalgebras. Maybe I have time later to look into this, right now I am busy with something else, so for the moment I am just forwarding the question here:

    I would like to ask a question about a paper by Goerss-Getzler on model category structure for DG coalgebras. In their Lemma 1.12.1 I dont get how the polynomials arive when computing the completion. According to me I could guess an argument if the DG coalgebra CC was supposed to be connected (i.e C_0 cong K the ). If for instance dim C_0 1, then I dont get their argument. Maybe you have a hint for me.

    Is the model structure on unbounded dg-coalgebras from Hinich 98 right proper, by any chance?
