Homology of Fibre Spaces: Elementary Theory,. The behavior of the homology groups is much more complicated. In the simplest case, that of a trivial fibration, the relationship is given by the Kimneth Theorem. The general case will be treated in Chapter XIII with the aid of the complicated machinery of spectral sequences.
