    We should have an entry on large N limit gradually. But sometimes it can be treated as a semiclassical limit. I quoted a reference by Yaffe where I originally read of that approach to the entry semiclassical expansion.

    added references on ’t Hooft double line notation for gauge group SO(N)SO(N) and unoriented worldsheets

    (I see that Predag Cvitanovic says in his Birdtracks book that he has something on this, but I haven’t extracted that yet.)

    He seems (p. 42) to be referring to Fig. 16 of this. Presumably he absorbed this into his Birdtracks notation.

    That’s it, Thanks!!

    I’ll be starting a dedicated entry ’t Hooft double line construction

    On the ’Literature’ tab of his site, he says that paper is superseded by his book,

    but contains interesting material (counting of invariants, graphs, etc.,) not included in the webbook.

    Thanks. Do you see where in the book this is? (BTW, finally found the pdf…)

    Thanks! Yes, that’s at least the case of 𝔰𝔲(N)\mathfrak{su}(N).

    Presumably the notation in (10.13) and (12.9) is giving those results for SO(n)SO(n) and Sp(n)Sp(n).

    I have re-written and considerably expanded the Idea-section.

    Also expanded and (re-)organized the list of references.
