Resumen:
The standard notions of asymptotically flat spacetimes have been challenged by
the examples found by Isaacson, Welling and Winicour, which show logarithmic asymptotic
behaviour. Here, a geometrical definition of general future asymptotically flat (GeFAF)
spacetimes is introduced, and its implications are systematically studied throughout the
paper. Conformal techniques are used, but no reference to field equations is made in this
work. In particular logarithmic behaviour is studied. For the general GeFAF case it is
deduced that the radiation fields always behave like l / r asymptotically.
