Spectrum of scalar curvature perturbations in Krein space quantization. (English) Zbl 1203.83077
Summary: The main goal of this paper is to derive the primordial power spectrum for the scalar perturbations generated as a result of quantum fluctuations during an inflationary period by an alternative approach of field quantization, i.e. Krein space quantization [J.-P. Gazeau, J. Renaud and M. V. Takook, Classical Quantum Gravity 17, No. 6, 1415–1434 (2000; Zbl 1131.83301); M. V. Takook, Int. J. Mod. Phys. 11, 509 (2002); S. Rouhani and M. V. Takook, Int. J. Theor. Phys. 48, No. 10, 2740–2747 (2009; Zbl 1177.83072)]. The spectrum of scalar curvature perturbations are calculated in the slow roll approximation.
