Moyal deformations, W1+∞ and celestial holography
Wei Bu, Simon Heuveline, David B. Skinner
Abstract
A bstract We consider the Moyal deformation of self-dual gravity. In the conformal primary basis, holomorphic collinear limits of the amplitudes of this theory show that it enjoys a perturbatively exact symmetry algebra LW ∧ that generalises Lw ∧ , the loop algebra of the wedge algebra of w 1+ ∞ , which appears in self-dual gravity.
