DESCRIPTION:I will show that self-dual gravity in Euclidean four-dimension
 al Anti-de Sitter space (AdS4) can be described by a scalar field with a c
 ubic interaction written in terms of a deformed Poisson bracket\, providin
 g a remarkably simple generalisation of the Plebanski action for self-dual
  gravity in flat space. This implies a novel symmetry algebra in self-dual
  gravity\, notably an AdS4 version of the so-called kinematic algebra. Thi
 s provides a concrete starting point for defining the double copy for Eins
 tein gravity in AdS4 by expanding around the self-dual sector.&nbsp\;
