Subject: A question about minimal model From: ssp@pdmi.ras.ru Date: Mon, 3 Apr 2006 20:09:51 +0400 (MSD) 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.
