WebHatcher 3.3.24 We will use the result from Hatcher that says a closed manifold of odd dimension has Euler char-acteristic zero. We know that H0(M;Z) = Z), and we are given … WebCf. Hatcher, section 3.A. If you are curious, you can read about the more general theory of derived functors in Lang's Algebra. (11/3) Explained the Kuenneth formula for the homology of a Cartesian product, following the approach in Bredon. It is instructive to compare this with the proof for CW complexes in Hatcher, section 3.B.
