    Should there be an entry ’I-II’, as mentioned here?

    Yes, it’s not a comprehensive list yet. More basic entries such as IIA - IIB are missing at the moment. On the other hand, it’s going to be a redundant list, too, since in the end there are several ways through the web of dualities between any given pair of limiting theories.

    Perhaps one day we can have a large diagram with many arrows.

    Thanks. But shouldn’t we group it under “QFT-QFT duality” instead of under “string-QFT duality”?

    I’d put it next to the item “KLT-relations”.

    Ok, Thank you very much

    I was not sure about the classification, since the Double Copy program wants to reach a well-defined duality between the whole NS-NS sector (g,B,ϕ)(g,B,\phi) and gauge fields

    I see. So what’s the picture here of the most optimistic case of the classical double copy construction? Do we think of it as being really a version of AdS/CFT?

    In any case, it might be good to group the “double copy” item together with the “KLT-relations”-item. These are close cousins, no?

    I know just that they would like to relate solutions of the field equations of (g,B,ϕ)(g,B,\phi) to the ones of a gauge field (see arXiv 1912.02177 for an example) in analogy with what happens in scattering amplitudes (see arXiv 1807.09859 for example). The relation with AdS/CFT is completely obscure, as far as I asked!

    Yes, I definitely agree about grouping them: they are cousin, even if the scattering amplitude version of double copy are more specifically the BCJ(Bern-Carrasco-Johansson)-relations (which may deserve a page or a section in the KLT-relations one).

    Okay, thanks. So I have regrouped now to read as follows:

    Here the parenthetical “super” should serve to imply the presence of KR- fields and dilaton fields.

    Thank you very much, it looks good!

    Adding “super” is very appropriate also because this gravity(gauge theory) 2\text{gravity} \sim (\text{gauge theory})^2 duality should have its supergravity counterpart
