    Hello, I thought that a new entry would be a good thing. Just a sketch for now.

    I’m going to make Ehlers transformation link to its own page here. This is preferable to linking to Wikipedia. Maybe someone can add to that page.

    I think you can’t have a link in a title heading, so I removed the one for ’S-duality’ from ’Double copy and S-duality’. It seems to generate a new number in the list of contents.

    I have added hyperlinks to a few more keywords (such as pp-wave).

    Just to notice that at the beginning of the entry, around “We thus call…” is currently a logical gap: the single copy gauge field has only been defined at this point, but no comment is made yet on what this has to do with anything. Some further sentence should be inserted here.

    Thank you, I made a change and I hope that part is less sketchy now

    Thanks. But what I feel is still missing is a mentioning of how, with these definitions of a gauge field from a Kerr-Schild metric and vice versa, the respective field equations imply each other. That’s what fills these definitions with substance.

    Thanks, I added something about it, but it’s still very sketchy

    Okay, thanks.

    Just on the formatting: I have indented some source code text to make all that is intended to be one bullet item also appear indented as such in the output.
