Abstract

One of the major advantages of the inflationary scenario is that it 
provides a mechanism for the generation of density perturbations in the 
early universe. These perturbations leave an imprint on the cosmic 
background radiation which has been observed. It has been shown that 
physical processes at and beyond the Planck scale could affect the 
spectrum of the density perturbations and thus leave an imprint on the 
cosmic background radiation. The questions of what types of imprints are 
possible and under what conditions they can be observed will be addressed.
