For each odd integer p > 1, infinitely many pairwise non-diffeomorphic irreducible smooth structures are constructed on a definite 4-manifold with infinite fundamental group whose abelianization is Z/2pZ × Z/2Z.

Smooth structures on definite four-manifolds with infinite fundamental group
For each odd integer p > 1, infinitely many pairwise non-diffeomorphic irreducible smooth structures are constructed on a definite 4-manifold with infinite fundamental group whose abelianization is Z/2pZ × Z/2Z.
