Nonsymplectic 4-manifolds with one basic class

Ronald Fintushel and Ronald J. Stern

Vol. 194 (2000), No. 2, 325–333
Abstract

We produce examples of simply connected 4-manifolds which have (up to sign) only one class with a nontrivial Seiberg-Witten invariant. Furthermore, these manifolds admit no symplectic structure with either orientation.
