Description
The first part will review the foundations of gravitational self-force theory in classical GR: a perturbative approach to the 2-body problem based on a systematic expansion of the field equations in the mass ratio, assumed small. The second part will describe recent work to apply self-force methods to the black-hole scattering problem, including a comparison with post-Minkowskian results from Amplitude calculations in a scalar-charge toy model.
