A comparatively long and technical section “From hom-functors to units and counits” (on adjoint functors) was sitting inside the Idea-section of adjunction. It seemed plainly misplaced there, and distracting attention from what should be the content of this entry, as opposed to the entry adjoint functor. So I have moved it now to where it seems to belong: inside the Examples-section.

The diagrams in Direct Definition do not seem to be rendering properly. (Not really my observation; I was alerted in a chat room at MO).

Probably need to be re-done with tikz.

Thanks. I have added the publication data, too.

Hmm, but maybe these should be in adjoint functor. We’re running this page adjunction as an abstract 2-categorical concept, although ’adjoint functors’ makes up a large chunk of the page as an example.

Yeah, I have already done some harmonizing of the list of References to both entries. That’s just the way it is now. At least each References section is now alerting the reader to also look at the other.
