Subject: Triquotient assignments for geometric morphisms
Date: Mon, 22 Jun 2009 16:48:54 +0100 [thread overview]
Message-ID: <E1MItdF-0001bp-AL@mailserv.mta.ca> (raw)
Has anyone generalised the theory of (weak) triquotient assignments
from locale maps to geometric morphisms? In particular, does the
pullback (assuming boundedness) of a geometric morphism with a
triquotient assignment have a unique triquotient assignment satisfying
the Beck-Chevalley condition?
Also, if f:X->Y is a continuous function between topological spaces,
are there any reasonable conditions (other than openness) under which
the interior of the direct image along f is a weak triquotient
assignment for the inverse image map?
Thanks,
Barney.
