Decomposing the chain complex into images and kernels (because we are over a field) and using the equivalence relation in 1) you can reduce this into the even and odd homology. | |

edited first sentence

| Dec 14, 2011 at 8:07 | comment | added | Andrew Stacey | I guess it's just language, but the first sentence grates. There are lots of ways of getting the zeroth space of BU x Z and these are two of them. Your first sentence implies (for me, at any rate) that these are the only two. | |
