Can the conformal factor of the gravitational field be a physical degree of freedom?
The role of the conformal factor was analysed in two gauge-invariant perturbative formulations. Using the classical and quantum linearized perturbation approach given by Mukhanov et al (1992 Phys. Rep. 215 203), the non-physical behaviour of the conformal perturbation as an isolated degree of freedo...
