Subject: String diagrams, adjunction and autonomous categories.
Date: Sun, 29 Aug 2010 05:48:18 +0000 [thread overview]
Message-ID: <E1Opsas-00015K-Qf@mlist.mta.ca> (raw)
As shown by Baez, in an autonomous category the isomorphism hom(A (X) B, C)
= hom (B, A -o C), when drawn as a string diagram, is like the bending of
the input wire A to make it an output.
Now one can also draw string diagrams to represent the zigzag equations
between the adjoint pair of functors _ (X) B and B -o _.
How does the latter diagram relate to the former one?
