Scientific paper

The author has derived second-order differential equations for cosmological perturbations, using gauge-invariant variables in a Friedmann - Lemaître - Robertson - Walker background, for each of the following gravity theories: f(R) gravity; generalized scalar-tensor gravity; gravity with nonminimally coupled scalar field; and induced gravity. Assuming a spatially flat background, each equation is put into a form suggested by Mukhanov, and asymptotic solutions are derived for the large- and small-scale limits.
