Subject: separable locale
Date: Tue, 30 Jun 2009 15:26:00 +0200 [thread overview]
Message-ID: <E1MNTTT-0006bl-Qs@mailserv.mta.ca> (raw)
Recently rereading Fourman's "Continuous Truth" I came across the term
"separable locale" but could nowhere find an explanation. Does it mean a
cHa A for which there exists a countable subset B such that ever a in A is
the supremum of those b in B with b leq a. This would be the point free
account of "second countable", i.e. having a countable basis.
Of course, second countable T_) spaces are separable, i.e. have a
countable
dense set.
Is this reading the "usual" one?
