Dear John,
I want you and everyone know that the definition of a braiding in your notes
* John Baez, Some definitions everyone should know.
http://math.ucr.edu/home/baez/qg-winter2001/definitions.pdf
is wrong. The notes were recently publicised by Toby.
But the definition given in the nLab
http://ncatlab.org/nlab/show/braided+monoidal+category
is correct.
Best,
André
