Equivariant connected sums of compact self-dual manifolds
We present an equivariant version of the Donaldson-Friedman programme for constructing self-dual conformal structures on connected sums of compact self-dual manifolds. LeBrun's examples on connected sums of complex projective planes are reconsidered and new examples with torus symmetry and some with circle symmetry are constructed.
