On the initial conditions of scalar and tensor fluctuations in $$f(R,\phi )$$ f(R,ϕ) gravity
Abstract We have considered the perturbation equations governing the growth of fluctuations during inflation in generalized scalar tensor theory $$f(R,\phi )$$ f(R,ϕ) . We have found that the scalar metric perturbations at very early times are negligible compared to the scalar field perturbation, ju...
