In what follows (E, p, B) will always denote a fibering in the sense of Serre, † with arc-wise connected base B, projection p:EB, and fibre F = p−1(b), b xs025B B. Coefficients will always be taken in a commutative ring A with a unit element, and the cohomology will be singular (cubical), as in (3).
