Conformally Einstein anti-self-dual spaces and their generalisations
Timothy Moy
We study the existence of Einstein scales and compatible metrics in Grassmannian geometry. As a special case, this includes the conformal-to-Einstein problem for anti-self-dual (AS…

Heavenly equations in de Sitter space
Maciej Dunajski, Timothy Moy
We demonstrate that all anti-self-dual Einstein metrics with non--zero cosmological constant locally arise from solutions of a single second order PDE introduced by Lipstein an…
