The generality of inflation in some closed FRW models with a scalar field

TL;DR

This paper investigates how likely inflation is in closed FRW universe models with scalar fields, considering different initial conditions and models, and compares these results with previous models involving perfect fluids.

Contribution

It extends the analysis of inflation probability to models with brane and complex scalar fields, highlighting the impact of initial condition measures.

Findings

Inflation likelihood varies with initial condition measures.

Models with scalar and complex scalar fields show different inflation probabilities.

Comparison with perfect fluid models reveals differences in inflationary behavior.

Abstract

The generality of inflation in closed FRW Universe is studied for the models with a scalar field on a brane and with a complex scalar field. The results obtained are compared with the previously known results for the model with a scalar field and a perfect fluid. The influence of the measure chosen in the initial condition space on the ratio of inflationary solution is described.
