Scalar Curvature and Connected Sums Of Self-Dual 4-Manifolds

Abstract

Under a vanishing hypothesis, Donaldson and Friedman proved that the connected sum of two self-dual Riemannian 4-Manifolds is again self-dual. Here we prove that the same result can be extended over to the positive scalar curvature case.
