(Dated: August 3, 2011)We briefly review the need to perform renormalization of inflationary perturbations to properlywork out the physical power spectra. We also summarize the basis of (momentum-space) renormal-ization in curved spacetime and address several misconceptions found in recent literature on thissubject.
