Abstract: (arXiv)
Inspired by interaction of gravitational waves and dark matters, we study the Bondi-Sachs formalism for Einstein massless scalar field with zero cosmological constant. We provide asymptotic expansions for the Bondi-Sachs metrics as well as the scalar fields and prove the peeling property. We also prove the positivity of the Bondi energy-momentum under condition at some retarded time . This condition ensures that asymptotically null hypersurfaces near are asymptotically null initial data sets of order 2 and the positive energy theorem for null infinity can be applied.Note:
