In this talk, we will explore some similarities and differences when applying the methods of Melrose’s school of Geometric Scattering to Friedrich’s representation of spatial infinity. The context will be surrounding the study of massless fields in a neighbourhood of spatial infinity in the Minkowski spacetime, which satisfy linear wave equations. We compare these results with those obtained using methods developed by Friedrich. This is ongoing work in collaboration with E. Gasperin and J. Valiente Kroon.
