Subject: withdrawal of preprint
Date: Thu, 2 Jul 1998 22:10:56 -0400 (EDT) [thread overview]
Message-ID: <Pine.OSF.3.93.980702220817.15979D-100000@idol.union.edu> (raw)
In-Reply-To: <Pine.OSF.3.93.980624104635.6575A-100000@idol.union.edu>
The paper "Exponentiablity and Single Universes" by Marta Bunge and Susan
Niefield, recently announced on the site ww1.union.edu/~niefiels has been
temporarily withdrawn. A revised version will be posted soon. The paper
contained an erroneous result - namely, that for an arbitrary small
category B, the category UFL/B of Giraud-Conduche fibrations over B is a
topos. A counterexample has been found by Peter Johnstone.
