As a result, the inflationary scenario associated to this potential or to an action including an term are referred to as Starobinsky inflation. To distinguish, models using the original, more complete, quantum effective action are then called (trace)-anomaly induced inflation.
Paul Steinhardt, one of the original architects of the inflationary model, introduced the first example of eternal inflation in 1983. [97] He showed that the inflation could proceed forever by producing bubbles of non-inflating space filled with hot matter and radiation surrounded by empty space that continues to inflate.
Eternal inflation is a hypothetical inflationary universe model, which is itself an outgrowth or extension of the Big Bang theory. According to eternal inflation, the inflationary phase of the universe's expansion lasts forever throughout most of the universe. Because the regions expand exponentially rapidly, most of the volume of the universe ...
It is the inflation accounting model required in International Financial Reporting Standards implemented in 174 countries. Process of Inflation Accounting Inflation Accounting refers to the process of adjusting the financial statements of a company to show the real financial picture of the company during the inflationary period. Inflation ...
Most inflationary models propose a scalar field called the inflaton field, with properties necessary for having (at least) two vacuum states. It is not known exactly when the inflationary epoch ended, but it is thought to have been between 10 −33 and 10 −32 seconds after the Big Bang. The rapid expansion of space meant that any potential ...
Other economic concepts related to inflation include: deflation – a fall in the general price level; [17] disinflation – a decrease in the rate of inflation; [18] hyperinflation – an out-of-control inflationary spiral; [19] stagflation – a combination of inflation, slow economic growth and high unemployment; [20] reflation – an ...
The inflaton field is a hypothetical scalar field which is conjectured to have driven cosmic inflation in the very early universe. [1] [2] [3] The field, originally postulated by Alan Guth, [1] provides a mechanism by which a period of rapid expansion from 10 −35 to 10 −34 seconds after the initial expansion can be generated, forming a universe not inconsistent with observed spatial ...
Linde continues his work on the theory of inflationary multiverse. In particular, Renata Kallosh and Andrei Linde, together with their collaborators, developed a theory of cosmological attractors. This is a broad class of versions of inflationary cosmology which provide one of the best fits to the latest observational data. [5]
