PT Journal AU Agullo, I Navarro-Salas, J Olmo, GJ Parker, L TI Remarks on the renormalization of primordial cosmological perturbations SO Physical Review D JI Phys. Rev. D PY 2011 BP 107304 EP 5pp VL 84 IS 10 DI 10.1103/PhysRevD.84.107304 LA English AB We briefly review the need to perform renormalization of inflationary perturbations to properly work out the physical power spectra. We also summarize the basis of (momentum-space) renormalization in curved spacetime and address several misconceptions found in recent literature on this subject. ER
