This article is a rst step in establishing a link between the Donaldson polynomials and Seiberg-Witten invariants of a smooth 4-manifold. As the result of analysis of the structure of the Donaldson's invariant of a smooth simply connected 4 manifold X Kronheimer and Mrowka K-M1] (see also F-S]) proved the existence of k X classes such that the Donaldson's invariant of X is deened uniquely by th...
