I won’t be impressed until they generalize to an *n*+1 page proof of the *n* color theorem.

Just to jump in because I don't know where else I would ever mention this, I just found out the other day that other geometries (?) have different maximally-necessary (?) colors. A torus has 7 for instance. On a sphere is equivalent to planar. I'm just reading this from wikipedia now, but I think it's super neat.

Cheering from the sidelines here.

Ok, this is pretty big. Never have I ever been excited by a tweet than now.

While doing my Phd, I've always heard from some of my older peers about the controversies surrounding the classic Appel and Haken computer based proof (there were more controversies other than the use of computers for the proof, please don't ask me for details).

Also, some more recent problems, like the Hill conjecture in crossing numbers, are also stuck in the computational hell, that is, even using computers it still took years to advance. Hopefully this proof will shed some light that may help with these problems.

Not to piss on anyone's cheesecake here, but whilst these are two well-respected mathematicians from a good department, they're both retired and haven't been especially active in research lately (we're talking perhaps a decade or more since any substantial work).

I'd take this with a pinch of salt until more concrete details appear. I'd obviously be thrilled if it were true though!

Wow this is really exciting, 2 color and 6 color were what really helped me understand graph theory when I first started

It doesn't exactly inspire confidence that both the authors are professor emeriti. I'm not a graph theorist, but I find it exceedingly unlikely that such a short proof could've been missed all this time.

Edit: I removed the part about the last published paper, because it seems to simply be their page not being updated.
