Jan 11, 2010 at 4:56 comment added Mike Shulman Well, both have a diagonal that is "closed" relative to some ambient closure operator. I'm not sure that the closure operators are related in any way---one is closure in the point-set-topological sense, while the other is closure of sieves relative to a Grothendieck topology.
