Classical and quantum cosmology in Einstein–æther scalar–tensor gravity: Noether symmetry analysis

This work deals with Einstein–æther scalar–tensor gravity in the background of homogeneous and isotropic flat FLRW space–time model. The Noether symmetry vector identifies a transformation in the augmented space so that the field equations become solvable. The cosmological solutions are analyzed from the observational point of view. Finally, for quantum cosmology, the Wheeler–DeWitt (WD) equation has been formulated and solutions have been determined by identifying the periodic nature of the wave function using conserved (Noether) charge.
