Is it possible to compute the minimal model (in the sense of Sullivan)
of a closed oriented manifold geometrically, using geometric chains
(in any sense) instead of differential forms - and the intersection
pairing? The difficulty is that chains do not form an algebra, because
the intersection of two chains is well defined only if they are
in general position. Massey triple products may be computed geometrically
(just choose everything generically), but this is not enough to construct
the minimal model.
