After writing this paper we learned that this result was also known to Kronheimer and Furuta. This theorem is closely related to the work of Fintushel and Stern [FS1], [FS2]. They proved that any homotopy K3 surface which contains a smoothly embedded Σ(2, 3, 7) has nontrivial SU(2) Donaldson invariants mod 2. Note that Theorem 1.1 and the folk conjecture, (cf. [W]), on the relation between Donaldson and Seiberg-Witten invariants would imply that every homotopy K3 surface has nontrivial SU(2) Donaldson invariants mod 2. As a straightforward corollary of Theorem 1.1 and the adjunction inequalities for the Seiberg-Witten basic classes [KM], [MSzT], [D2] we get the following:
