Subject: Giraud_Elementary_?
Date: Mon, 7 Nov 2016 16:03:18 -0500	[thread overview]
Message-ID: <E1c3vRS-0003x7-0b@mlist.mta.ca> (raw)

Hi, in this posting I will use the terminology used by most people in
the list.

There are Grothendieck, Giraud and Elementary (Lawvere-Tierney) topos.

Grothendieck are Giraud and Elementary, my question is:

Are Elementary Giraud topos which are not Grothendieck ?

Examples ?

greetings  e.d.
