John Baez (Sep 19 2020 at 00:32):I'm trying to evaluate this paper:
These are fibrations of graphs, not of categories - though apparently a "fibration of graphs" is a map of graphs such that the corresponding map between free categories is a Grothendieck fibration.
I've convinced myself this is not a crackpot paper, even though it mentions "fractal golden ratios of Fibonacci sequences" in the abstract. I'm trying to figure out what it really says.

How did that get past the referees PNAS selected??
John Baez (Sep 19 2020 at 05:37):Actually the paper looks okay, believe it or not!
John Baez (Sep 19 2020 at 05:38):That particular phrase is stupid, but there's stuff about Fibonacci numbers in the paper, which is apparently not the interesting part.
