Embedding of two-dimensional CW complexes which induces a zero homomorphism on second homotopy groups
Are you sure $K_2\to K_3$ induces a zero map on $\pi_2$? Why? |

Unifying Geometry for Characteristic Classes
(Re: unifying 2 and 4) I don't remember any details but there certainly is an algebraic version of $H(BG)\to H(M)$: the algebraic version of (de Rham complex of) $G\to EG\to BG$ is a contractible complex $\Lambda g[1]\otimes Sg[2]$ — and a connection gives a map from this guy to the de Rham complex of $M$ — something like that... |
