    Added stub for Kontsevich formality.

    Also added some comments to the HKR page.

    Thanks!! I added some links to Kontsevich formality.

    I have opened a new stub formality and removed the (improper) redirect formality at the more specialized entry Kontsevich formality. More references at Kontsevich formality.

    More material both at formality and at Kontsevich formality.

    at Kontsevich formality it used to say that “therefore every Poisson manifold has a canonical formal deformation quantization”.

    This is not really true, the quantization is canonical only up to an action of the Grothendieck-Teichmüller group.

    I have now added a super-brief remark on this, and then added a super-brief remark on formality of the E nE_n-operad in char 0 for all nn, which makes an analogous statement for the deformation quantization of higher dimensional quantum field theories.

    I don’t have time right now to do this justice at all. What is in the entry now is really just a reminder note for myself to come back to later. Of course if it inspires anyone to add more discussion, I won’t complain.

    It would be better if this were named
    Kontsevich formality theorem

    the notion of formality is not modified by maxim
