A Comment on "Brans-Dicke Cosmology with a scalar field potential"
J\'er\'emie Vinet
TL;DR
This paper critiques a recent publication on Brans-Dicke cosmology, revealing that it used incorrect equations, thus invalidating its claimed solutions and conclusions.
Contribution
It identifies and corrects errors in the foundational equations of a previous study on Brans-Dicke cosmology.
Findings
The previous solutions are based on flawed equations.
The original results are invalid due to these errors.
Correct equations lead to different cosmological solutions.
Abstract
We show that a recent letter claiming to present exact cosmological solutions in Brans-Dicke theory actually uses a flawed set of equations as the starting point for their analysis. The results presented in the letter are therefore not valid.
