Higher dimensional Bondi energy with a globally specified background structure
Higher dimensional Bondi energy with a globally specified background structure
A higher (even spacetime) dimensional generalization of the Bondi energy has recently been proposed (Hollands and Ishibashi 2005 J. Math. Phys. 46 022503) within the framework of conformal infinity and Hamiltonian formalism. The gauge condition employed in Hollands and Ishibashi to derive the Bondi-energy expression is, however, peculiar in the …
