Generalized Brans–Dicke inflation with a quartic potential
Within the framework of Brans–Dicke gravity, we investigate inflation with the quartic potential, λφ4/4, in the presence of generalized Brans–Dicke parameter ωGBD(φ). We obtain the inflationary observables containing the scalar spectral index, the tensor-to-scalar ratio, the running of the scalar sp...
