Classical predictive electrodynamics in a conformally flat universe. The case of the Einstein-de Sitter universe

We give a natural extension of predictive relativistic mechanics to the case when the interaction background is a curved space-time instead of Minkowski space. The case of a conformally flat universe is considered and then we study the predictive electrodynamics of such a space. Finally we treat the more particular case of the Einstein-de Sitter universe and we do some rough estimates for the early Universe.
