Abstract: (Elsevier)
We study the dynamical correspondence between the scalar fluctuation spectrum and the inflationary potential V ( φ ) and consider a power law spectrum with index β as an example. We show that for the range of β relevant to the interpretation of COBE observations, this correspondence is fragile, in the sense that small changes in β could produce dramatic changes in the corresponding V ( φ ). This is of potential significance for the reconstruction of V ( φ ) from such observations and also in the wider context of inflationary models in which V ( φ ) is specially chosen to produce a desired spectrum and dynamics.- inflation
