Abstract

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_\wedge that generalises Lw_\wedge, the loop algebra of the wedge algebra of w_1+∞, which appears in self-dual gravity.
