Nondiffeomorphic Symplectic 4-Manifolds with the same Seiberg-Witten Invariants

Ronald Fintushel, Ronald J Stern

Abstract. The goal of this paper is to demonstrate that, at least for nonsimply connected 4-manifolds, the Seiberg-Witten invariant alone does not determine diffeomorphism type within the same homeomorphism type.

Keywords. Seiberg-Witten invariants, 4-manifold, symplectic 4-manifold
