    I was just reminded of John Baez years ago describing Bar-Natan’s paper on the four-color problem and the relation between SU(2)SU(2) and SU(n)SU(n) gauge theory. Bar-Natan’s paper is here.

    Thanks, excellent. So let’s add that to all related entries:

    On the logical equivalence between the four-colour theorem and a statement about transition from the small N limit to the large N limit for Lie algebra weight systems on Jacobi diagrams via the ’t Hooft double line construction:

    I wonder if Bar-Natan didn’t know that the double line construction he uses so effectively is earlier due to ’t Hooft, or if he intentionally chose to never cite him. Seems a curious omission.

    That would be fun if M-theory could help out with the four-colour problem!
