Singular Monopoles and Gravitational Instantons
Abstract
We model Ak and Dk asymptotically locally flat gravitational instantons on the moduli spaces of solutions of U(2) Bogomolny equations with prescribed singularities. We study these moduli spaces using Ward correspondence and find their twistor description. This enables us to write down the K\"ahler potential for Ak and Dk gravitational instantons in a relatively explicit form.
