Date: Fri, 18 Aug 2000 18:50:44 +0200 From: Max Karoubi Subject: Re: EM-space for the reals One possible reply is the following : K(n,real numbers R) is the realization of the simplicial vector space which is defined in dimension p as the set of closed differential forms of degree n on the canonical affine space in R^{p+1} See for instance : H. Cartan. Theories cohomologiques. Inv.
