Quintessence Problem and Brans-Dicke Theory

TL;DR

This paper demonstrates that Brans-Dicke theory within an anisotropic cosmological model can independently address the quintessence problem and explain accelerated expansion without additional matter, also discussing the flatness problem.

Contribution

It shows that Brans-Dicke theory alone can solve key cosmological problems in anisotropic models, without requiring quintessence matter.

Findings

Brans-Dicke theory explains accelerated expansion without quintessence.

The flatness problem is also addressed within this framework.

Anisotropic models are effective in solving cosmological issues.

Abstract

It has been shown that Brans-Dicke (BD) theory in anisotropic cosmological model can alone solve the quintessence problem and we have accelerated expanding universe without any quintessence matter. Also the flatness problem has been discussed in this context.
