Abstract

We present cosmological perturbation theory based on generalized gravity theories including string correction terms as well as a tachyonic complication. The classical evolution as well as the quantum generation processes in these variety of gravity theories are presented in unified forms. These apply both to the scalar- and tensor-type perturbations.
