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 [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
