I will talk about the diffeomorphism classification of 4-manifolds up to
connected sums with the complex projective plane, and how the resulting
equivalence class of a manifold can be detected by algebraic topological
invariants of the manifold. I may also discuss related results when one
takes connected sums with another favourite 4-manifold, S^2 x S^2, instead.
