    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.

    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
