Scientific paper

The scalar-type metric perturbations in the isotropic universe in R2 gravity are considered. The action for such perturbations in terms of gauge invariant variables is obtained and a self-consistent quantum theory is constructed. The spectrum of inhomogeneities in the inflationary universe is calculated.
