Subject: weak double categories?
Date: Wed, 26 Oct 2005 13:08:41 -0700 (PDT) [thread overview]
Message-ID: <E1EVEI7-0001JV-6G@mailserv.mta.ca> (raw)
Dear Categorists -
If you weaken the notion of 2-category you get the notion of
bicategory. Has anyone tried to correspondingly weaken the
notion of double category, so that a bicategory is a special
sort of "weak double category" in analogy to the ways in which
a 2-category is a special sort of double category? Did anyone
succeed?
Best,
jb
