Comment about the "Gravity coupled to a scalar field in extra dimensions" paper

TL;DR

This paper challenges prior claims that solutions for gravity coupled to a scalar field in higher dimensions cannot be expressed in Schwarzschild coordinates, providing a counterargument to previous objections.

Contribution

It demonstrates that the previous assertion about the impossibility of expressing solutions in Schwarzschild coordinates is incorrect.

Findings

Counterexamples to prior claims

Solutions can be expressed in Schwarzschild coordinates in higher dimensions

Clarification of the conditions for scalar-gravity solutions

Abstract

Wehus and Ravndal have argued that in d + 1 dimensions the general solution for gravity minimally coupled to a scalar field can not be explicitly written in Schwarzschild coordinates. We contest these objections.
