Spectrum of Initial Perturbations in Open and Closed Inflationary Models

Astrophysics 2007-05-23 v1

Abstract

Spectrum of initial scalar and tensor perturbations created during an inflationary stage producing a closed or open FRW universe now is discussed. In the closed case, the CMB temperature anisotropy ΔT/T{\Delta T/T} generated by scalar perturbations is enhanced for low multipoles. It is argued that in the open case there is no suppression of low multipoles. A possibility of the existence of a preferred space direction in the open case is noted.
