Generalized asymptotics for gauge fields

Understand

An interesting question is to characterize the general class of allowed boundary conditions for gauge theories, including gravity, at spatial and null infinity.

• This has played a role in discussions of soft charges, where antipodal symmetry has typically been assumed.
• However, the existence of electric and gravitational line operators, arising from gauge-invariant dressed observables, for example associated to axial or Fefferman-Graham like gauges, indicates the existence of non-antipodally symmetric initial data.
• This note studies aspects of the solutions corresponding to such non-symmetric initial data.
