Enrico Zoli [Wed, 17 Jan 2007 17:59:59 +0000 (17:59 +0000)]
This is the roadmap of the constructive proof of Lebesgue's dominated
convergence theorem in the order theoretic setting. I.e. we speak of
convergence (in terms of liminf and limsup) and not of norms/measures.

The formulation should be fully constructive:
 1. the exceeds relation is used in place of the derived negative notion
    <= for partial orders
 2. strong sup and infs are used in place of the weaker sup and infs
 3. the statement of Lebesgue's dominated converge theorem is just
    extensionality of the functional
      \lambda f. liminf f a_n
    with respect to the apartness relation # over real numbers and the
    exceeds/apartness relation over partial orders.

Interesting points to be noticed:
 a) one lemma used in the proof is Fatou. This lemma can be given in the
    usual negative formulation (i.e. on <=)
 b) another lemma used in the proof is that the liminf is less or equal to
    the limsup. This lemm can be given in the usual negative formulation
    (i.e. on <=). Moreover, we feel that if <= is not defined as
    ~< it is actually impossible to constructively prove it.

There used to be two minimal joins between an ordered_set and an abelian_group:
ordered_field_ch0 and riesz_space. To avoid the problem without introducing
backtracking in unification I have introduced ordered_abelian_groups.
An ordered_field_ch0 is recast as a field that is also an ordered_abelian_group
and a cotransitively_ordered_set. I still have to recast riesz_spaces as
vector spaces that are also ordered_abelian_groups and lattices.

1. More debugging code
2. "Bug" "fixed": when the pullback of two coercions is computed, only the
   join is returned, but not the two coercions that complete the pullback.
   Thus we need to recompute them and it may happen that we find more than one
   parallel coercions. This "fix" just randomly picks the first one (instead
   of raising an assert false). All this stuff must be handled in a better way.
