Vladimir Folomeev
TL;DR
This paper analyzes a flat anisotropic early Universe model with two interacting scalar fields, providing analytic solutions that show the universe evolves towards isotropy during inflation.
Contribution
It introduces a specific potential energy form for two interacting scalar fields and derives analytic solutions for inflationary and scalaron stages.
Findings
Solutions tend asymptotically to isotropic Friedmann model
Analytic solutions for inflationary and scalaron stages are obtained
Model demonstrates isotropization during early universe evolution
Abstract
The flat anisotropic model of the early Universe is considered. Two interacting scalar fields with special form of potential energy are a source of matter fields. Analytic solutions for inflationary and scalaron stages are found. It is shown that the solutions tend asymptotically to isotropic Friedmann model.
