“…This result is a generalization to arbitrary dimension of the result derived by Frolov in Ref. [42] and coincides with the formula obtained by Lemos and Thompson [31]. It should be noted, however, that the derivation presented here is simpler.…”

We investigate the vacuum polarization, φ 2 , of the quantized massive scalar field with a general curvature coupling parameter in the spatially-flat N -dimensional Friedman-Robertson-Walker spacetime with 4 ≤ N ≤ 12. The vacuum polarization is constructed using both adiabatic and Schwinger-DeWitt approaches and the full final results up to N = 7 are explicitly demonstrated. The behavior of φ 2 for 4 ≤ N ≤ 12 is examined in the exponentially expanding universe, in the power-law and inflationary powerlaw models. In the case of exponential expansion, φ 2 is constant and for a given mass it depends solely on the Hubble constant and the curvature coupling parameter. In the power-law models its behavior is more complicated and, generally, decays in time as t −n , where n/2 is the integer part of N/2. The 2 + 1-dimensional case is also briefly analyzed. The relevance of the present results to the stress-energy tensor is examined.
