On the problem of initial conditions for inflation

TL;DR

This paper reviews the initial conditions problem in inflationary cosmology and discusses solutions for various models, especially those with plateau potentials supported by recent observations.

Contribution

It provides an overview of the current status and proposes methods to address initial conditions for a wide range of inflationary models.

Findings

Several solutions to initial conditions problem are identified.

Models with plateau potentials are compatible with these solutions.

The review clarifies the status of initial conditions in modern inflationary theory.

Abstract

I review the present status of the problem of initial conditions for inflation and describe several ways to solve this problem for many popular inflationary models, including the recent generation of the models with plateau potentials favored by cosmological observations.
