Webk-complex k=˘where we identify all faces of the same dimension. The homology of X is H n(Xk) = 8 >< >: Z n= 0 Z n= kand n is odd 0 otherwise Proof. Since Xkis a -complex, to compute the singular homology H n, we can just compute the simplicial homology H n (because of Theorem 2.27, Hatcher pg 128). Since Xkhas exactly one simplex in each ... http://match.stanford.edu/reference/topology/sage/topology/delta_complex.html
WebHomology with coefficients can, in some instances, tell us things that ordinary homol-ogy can’t. For example, X = RP2 has reduced homology Z2 in dimension 1 only, and so the … WebExamples of such invariants include homology, cohomology, and the Eu-ler characteristic. Thus we can define H∗(π) := H∗(X) (0.1) if X is an aspherical space with fundamental group π, and similarly for cohomology and the Euler characteristic. [We will replace (0.1) with an equivalent algebraic definition in the next section.]
WebAs in part (a), the homology of Y vanishes in degree greater than 2, and the degree 0 homology is isomorphic to Z, so we only need to look at degrees 1 and 2. The map from H 1(S1) ˘=Z to H 1(RP2) H 1(M) ˘=Z 2 Z takes ato ( a;2a). This is injective, so H 2(X) ˘=H 2(RP2) H 2(M) = 0. As above, H 1(X) is isomorphic to the cokernel of this map, WebJul 31, 2012 · Homology of RP2 without triangulation About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features NFL Sunday …

No, Pi_2(RP^2 v S^3) is NOT equal to H_2(RP^2 v S^3). (Hurewicz theorem can't be applied because RP^2 v S^3 is not simply connected).
