28th International Cosmic Ray Conference 3145 Bondi Mass in Scalar Fields

The asymptotically flat space-time with scalar fields is studied. It shows that the concepts of Bondi mass, Bondi mass loss, etc., are also applicable to other fields, although they were originally defined by gravity. The generating formulae of Bondi mass loss and angular momentum loss by a dynamics Hamiltonian over a hyperboloid are given by the linearised theory. 1
