Abstract In this paper we define cohomology operations moduli space of cohomology operations flows" in a manifold, and use them to define analogues of Donaldson invariants. Throughout there have been two basic points: A stable cohomology operation of degree will be a collection of homomorphisms for eachwhich are natural in the spaceand which commute with the suspension isomorphisms.

If we think of as represented by a spectrumso that is a representable functor in the stable cohomology operations categorythen a stable cohomology operation comes from a homotopy class of maps of degree. Of course, there exist well--known methods for computing co homology groups, for example, the reduction algorithm consisting in reducing the matrices corresponding to the differential in each dimension to the Smith normal form, from which one can read off co homology groups of cohomology operations complex, or the cohomology operations algorithm due to Edelsbrunner et al.
