DESCRIPTION:Using the twistor connection\, we introduce a symplectic struc
 ture on\nthe &nbsp\;space of conformal Einstein spacetimes. This leads to 
 the\ndefinition of conformally invariant symplectic potentials\, charges a
 nd\nfluxes. Their &nbsp\;advantage is the regularity at the boundary of th
 e\nconformal completion of spacetime (scri) with a non-zero cosmological\n
 constant without extra holographic\n&nbsp\; renormalization.
