Asymptotic flatness at null infinity in higher dimensional gravity
Seminar Room 1, Newton Institute
We give a geometrical definition of the asymptotic flatness at null infinity in higher (even) dimensions within the framework of conformal infinity. We discuss the stability of our definition against perturbations to linear order. Then, we derive a higher (even) dimensional version of the Bondi-energy within the Hamiltonian framework. We discuss why our definitions and constructions do not work in odd spacetime dimensions.
