Subject: question about discrete op-fibrations
Date: Tue, 31 Jan 2012 18:03:35 -0600	[thread overview]
Message-ID: <E1RsasQ-0002zc-9d@mlist.mta.ca> (raw)

Hi all,

Here's a quick question perhaps someone here can answer easily.

Let DOF denote the category whose objects are small categories C,D,
etc. and in which Hom(C,D) is the set of discrete op-fibrations C-->D.
For a category C, let DOF_{C/} denote the coslice over C.

Question: Does there exist a terminal object in DOF_{C/}?

Thanks!
David
