Date: Tue, 6 Jul 1999 13:25:14 -0500 (CDT) From: Hongseok Yang Subject: categories: Internal sheaf Does anyone help me to figure out what internal sheaf means? I mean, for any internal category (C0, C1, id, src, tgt, comp), there is a definition of a internal presheaf (also called category action). If it is, I want to know the canonical definition of an internal sheaf. Thanks in advance, Hongseok
