DESCRIPTION:After a review of symmetries and classical solutions involved 
 in the\nAdS3/CFT2 correspondence\, we apply a similar analysis to asymptot
 ically flat\nspacetimes at null infinity in 3 and 4 dimensions. In the spi
 rit of two\ndimensional conformal field theory\, the symmetry algebra of a
 symptotically flat\nspacetimes at null infinity in 4 dimensions is taken t
 o be the semi-direct sum\nof supertranslations with infinitesimal local co
 nformal transformations and\nnot\, as usually done\, with the Lorentz alge
 bra. As a first application\, we\nderive how the symmetry algebra is reali
 zed on solution space. In particular\,\nwe work out the behavior of Bondi
 ’s news tensor\, mass and angular momentum\naspects under local conforma
 l transformations.
