Inflation, holography, and the choice of vacuum in de Sitter space

TL;DR

This paper explores different de Sitter vacua in the context of holography, discussing their physical acceptability, implications for inflation, and potential links to cosmic microwave background radiation.

Contribution

It analyzes a family of de Sitter vacua within holography, offering a new perspective on vacuum selection and inflationary initial conditions.

Findings

Certain de Sitter vacua are physically acceptable in holography.

Inflationary scenarios can be interpreted through specific vacua.

Connections between vacuum choice and CMBR are proposed.

Abstract

A family of de Sitter vacua introduced in hep-th/0203198 as plausible initial conditions for inflation, are discussed from the point of view of de Sitter holography. The vacua are argued to be physically acceptable and the inflationary picture provides a physical interpretation of a subfamily of de Sitter invariant vacua. Some speculations on the issue of vacuum choice and the connection between the CMBR and holography are also provided.
