Abstract
Let R be either Fp or a field of characteristic 0. For each R-good topological space Y, we define a collection of higher cohomology operations which, together with the cohomology algebra H * (Y;R), suffice to determine Y up to R-completion. We also provide a similar collection of higher cohomology operations which determine when two maps f0,f1: Z→Y between R-good spaces (inducing the same algebraic homomorphism H * (Y;R)→H * (Z;R)) are R-equivalent.
