Subject: Commuting diagrams in a bicategory
Date: Tue, 12 Jan 2010 15:17:30 -0800 [thread overview]
Message-ID: <E1NV5AD-0002T8-FZ@mailserv.mta.ca> (raw)
I'm writing up the definitions of braided, sylleptic, and symmetric
monoidal bicategories and would like to reorient some of the
polyhedral coherence diagrams to make their symmetry more apparent.
All the 2-morphisms are isomorphisms and all the 1-morphisms are
equivalences. In such a case, it seems like any way of chopping up
the polyhedron into two "sides" will commute as long as one way does.
Is this common wisdom, or a folk theorem, or has someone proved it?
