World function and time transfer: general post-Minkowskian expansions
World function and time transfer: general post-Minkowskian expansions
In suitably chosen domains of space-time, the world function may be a powerful tool for modelling the deflection of light and the time/frequency transfer. In this paper we work out a recursive procedure for expanding the world function into a perturbative series of ascending powers of the Newtonian gravitational constant …
