In the context that we are framing our discussion, the scalar field is responsible for the inflationary expansion and the vector field is partly responsible of the generation of the primordial curvature perturbation [zeta].
In our context, the asymptotic region is located at super horizon scales when the inflationary perturbations evolve classically and carry the information of the physical mechanism that drives the inflationary expansion.
We don't solve the dynamics of the scalar field, we just assume some features of its solutions due to the fact that this field drives the inflationary expansion.
However, as recently pointed out by Agullo and Parker, when the corresponding stimulated creation is considered, the characteristics of the state of the universe at the onset of inflation are not diluted by the inflationary expansion and can be imprinted in the distribution of primordial inhomogeneities.
The second half of the book concerns ongoing questions: the roles of dark matter and dark energy; the rapid inflationary expansion of the early universe; the origins of the elements; and the origins, structure, and ultimate fate of the universe.
The only solution is for the German government to go inflationary expansion for the next few years, which would reduce the imbalance," he added.
Fed Chairman Alan Greenspan has acknowledged that this is a less inflationary expansion, in part because the Fed notched up interest rates in 1994.
In this regard, the reflationary policies of the mid 1930s may account for the price spike that Berry detects in 1938, but the length and strength of the wartime and post-war inflationary expansion would appear to have more to do with military expenditures than with institutional reforms undertaken in the 1930s.
The data presented suggest that the really unusual episode in this century occurred after WWII, when the length and strength of the inflationary expansion were unique by historical standards.
Some cosmologists have proposed thatour bubble, our universe, underwent a period of rapid, inflationary expansion in the past.
