Geometric inflation

Assisted Inflation from Geometric Tachyon

We study the effect of rolling of N D3-branes in the vicinity of NS5-branes. We find out that this system coupled with the four dimensional gravity gives the slow roll assisted inflation of the scalar field theory. Once again this expectation is exactly similar to that of N -tachyon assisted inflation on unstable D-branes. e-mail: [email protected] e-mail: [email protected]

The Relation Between Inflation and Inflation Uncertainty In Iran

Inflation and Eternal Inflation

The basic workings of inflationary models are summarized, along with the arguments that strongly suggest that our universe is the product of inflation. The mechanisms that lead to eternal inflation in both new and chaotic models are described. Although the infinity of pocket universes produced by eternal inflation are unobservable, it is argued that eternal inflation has real consequences in te...

Inflation Targets and Inflation Targeting

There is widespread agreement that price stability (in practice, low and stable inflation) should be an objective of monetary policy. This agreement is reflected both in the mandates set for monetary policy by governments and in the practice of central banks. Several other important questions about the objectives for monetary policy are less settled: Should there be other objectives? If there a...
