The cosmic model with cosmological constant ([LAMBDA]) satisfying EoS P = -[rho] is the usual example of cosmic inflationary model. The quantity [[rho].sub.[lambda]] decayed into ordinary matter with passage of time, leading to graceful exit from inflation and sustained the HBB model.

The standard inflationary model makes specific predictions about what this graph should look like.
healthcare industry is a constantly increasing, inflationary model. As a result, a large capital investment in automation that improves operational processes may be overlooked for smaller incremental expenses.
Bergliaffa (DFT/IF, UERJ, Rio de Janeiro) introduces a dozen contributions that follow developments arising from these discoveries and space missions in South America, e.g., observations of supernovae from the ESO Very Large Telescope in Chile, and WMAP5 data supporting the inflationary model of the universe.
"The existence of large-scale coherent features in the microwave background of this form would appear to contradict the inflationary model and would be a very distinctive signature of Penrose's model," said cosmologist David Spergel of Princeton University.
This being a cosmogonically philosophic problem of some significance, it would augur for the polemic that the mere existence of our own universe presupposes that it had a beginning, despite certain arguments from the inflationary model of astrophysics in recent years that it could have originated from nothing.
The simplest inflationary model is a single scalar field scenario in which inflation is driven by a scalar field called the inflaton that predicts adiabatic, Gaussian, and scale-invariant fluctuations [11].
Let us first observe the consequences of this inflationary model for the two first slow-roll parameters, whose explicit forms in the slow-roll regime are [45]
