Abstract

For this final chapter, we move to the early Universe to ask what constraints we can put on the violation of Lorentz invariance during inflation. As discussed in Sect.  2.2, we can use Einstein-aether theory (æ-theory) Jacobson and Mattingly (Phys. Rev. D64, 024028, (2001), [1]), Jacobson (PoS, QG-PH, 020, (2007), [2]) to model Lorentz violation in the boost sector, i.e., while maintaining rotational invariance on spatial hypersurfaces, at low energies.
