Quantum Fluctuations in Open Pre-Big Bang Cosmology
Abstract
We solve exactly the (linear-order) equations for tensor and scalar perturbations over the homogeneous, isotropic, open pre-big bang model recently discussed by several authors. We find that, in spite of claims to the contrary, vacuum quantum fluctuations, although parametrically amplified, remain negligible throughout the perturbative pre-big bang phase.Keywords
