Subject: Adjoints in bicategories
Date: Thu, 22 Jun 2000 14:45:07 +0200 (MET DST)	[thread overview]
Message-ID: <20000622124507.EF71C451D@mail.cs.uu.nl> (raw)

I'm looking for definitions of (the weak 2-dimensional analogues of 1-)
products and coproducts for bicategories, and also adjoints. In his 1967
article "Introduction to Bicategories, Part I" Benabou promises to treat
biadjoints in a sequel, but I gather this was never published. Gray treats a
notion of "quasi-adjointness" in "Formal Category Theory"; is this accepted as
the "right" generalization?

Pointers to definitions of these concepts in one of the approaches to weak
n-categories would be welcome as well.
