let us suppose that we are computing homology of a product where none of the requirements of künneth theorem are valid : is there a general way to compute the homology of such products?

Many thanks

    Well, with $\mathbb{Z}_2$ coefficients, which are the easiest to work with when considering real projective space, you *can* use the "basic" Künneth formula. If you want the integral (co)homology, then see the section in Hatcher I mentioned above. But it'll be more work, and you'll need to learn what Tor is if you don't know already (handily, Hatcher explains all in the preceding section).2011-05-20
