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