- Descrição
- We propose a new formulation for the \AE ther of Dirac based on a lagrangian approach. We analyse how the presence of a particular self-interaction term in the lagrangian lead us to a description of the \ae ther as being a medium with conductivity which is governed by macroscopic Maxwell equations with a polarization tensor $M_{\a\b}$ depending on the vector potential. These results are then applied to the analysis of the amplification of the primordial magnetic induction in a curved background of Friedmann's geometry.
