Description
Among the several approaches to quantise gravity, one particular is Horava-Lifshitz gravity, claiming that Lorentz symmetry is broken microscopically, which might allow a perturbative renormalisation of gravity. For this scenario to be related to the real world, Lorentz symmetry must be restored on large scales to be consistent with countless experiments. I propose a new foliated renormalisation group equation which preserves background diffeomorphism symmetry if the initial action is invariant. With this, it can be investigated whether quantum effects enhance or diminish Lorentz symmetry violations.
