(\widehat{sl_2}\) symmetry of ${\mathbb R}^{1,3}$ gravity

We propose novel asymptotically locally flat boundary conditions for Einstein Gravity without cosmological constant in four dimensions that are consistent with the variational principle. They allow for complex solutions that are asymptotically diffeomorphic to flat space-times under complexified dif...
