Hello,
I am taking as my concrete topos the category of irreflexive graphs.
>From William Lawvere's book (and many other sources), I know what the
subobject classifier looks like, i.e. what graph is the subobject
classifier. I haven't worked out the internal Heyting algebra Omega yet,
but Hom[1, Omega] consists of three arrows, yes? (Sorry I know the
question is a little basic, but I need a sanity check).
Thanks and regards, Bill Halchin
