Abstract | We apply the theory developed in quantum cosmology to a model of charged generalized Brans-Dicke gravity. This is a quantum model of gravitation interacting with a charged Brans-Dicke type scalar field which is considered in the Pauli frame. The Wheeler-DeWitt equation describing the evolution of the quantum Universe is solved in the semiclassical approximation by applying the WKB approximation. The wave function of the Universe is also obtained by applying both the Vilenkin-like and the Hartle-Hawking-like boundary conditions. We then make predictions from the wave functions and infer that the Vilenkin's boundary condition is more reasonable in the Brans-Dicke gravity models leading a large vacuum energy density at the beginning of the inflation. |
