Some Homological Algebra,ed algebraic topology. The reader is advised to skip this section (or skim it lightly) and refer back to it as necessary. We will omit some of the proofs; these are either easy or else can be found in standard texts, such as Dold [1972], Spanier [1966], or MacLane [1963].

Products,.′. Note that if . is projective over . and .′ is projective over .′ then . ? .′ is projective over .[. × .′]. In fact, it suffices to verify this in the case where . = . and .′ = .′, in which case the assertion follows from the obvious isomorphism . ? .′ ≈ .[. × .′].

Since we have this freedom of choice, it is reasonable to try to choose . (or . to be as “small” as possible, and this leads to various finiteness conditions on ..
