The aim of this project is to study candidates for Quantum Field Theories (QFT) dual to quantum gravity in four-dimensional asymptotically flat space-time. Secondly, we would like to carry out a systematic study of the classification of all possible supersymmetric extensions of the BMS 3 algebra, the asymptotic symmetry algebra of three-dimensional asymptotically flat space-times. The goals of the proposed project will strengthen the proposal of holography in the context of asymptotically flat space-time.
