Let $\mathbb{T}$ be the twistor space and consider deformations of its complex structure satisfying the first three conditions of the stated nonlinear graviton theorem: preservatio…

The asymptotic setting involves self-dual gravity, its Weyl Bianchi identities, conservation laws, and a suitable choice of asymptotic frame. Geiller's conjecture. The conservation…

Analytic continuation of the self-dual analog of the Kerr metric gives a real solution in Kleinian signature. After a simple diffeomorphism gauges away its angular momentum, the re…

In the setting of an anomaly-cancelled integrable theory of self-dual gravity, whose local operators are absent and whose S-matrix is trivial, the natural observables are expected…
