Description
We calculate gravitational effective action of the conformal scalar on the perturbed static spacetimes having topologies $S^1 × R^d$, $R × S^d$ and $S^1 × S^d$, generalizing well-known $R^{d+1}$ case. Then, exploiting Wess-Zumino action of conformal anomaly, we apply the result obtained to the problem of primordial perturbations in Early Universe.
