Since a covering maps each of the disjoint open sets of homeomorphically onto it is a local homeomorphism, i.e. is a continuous map and for every there exists an open neighborhood of , such that is a homeomorphism. It follows that the covering space and the base space locally share the same properties. WebIf an aspherical space Xis locally path connected the universal cover X˜ is contractible and X= X/G˜ . Also Hn(X) and Hn(X) depend only on π1(X). If G= π1(X) we may thus define Hn(G,Z) = Hn(X) and Hn(G,Z) = Hn(X) and because Xis determined up to homotopy equivalence the definition does not depend on X.
