Comment on "Construction of regular black holes in general relativity"

Understand

We claim that the physical parameters of the constructed black hole solutions in general relativity (GR) coupled to nonlinear electrodynamics (NED) by Zhong-Ying Fan and Xiaobao Wang in the Paper [Phys.

• Rev.
• D 94, 124027 (2016)] are misinterpreted, despite the formalism being correct.
• We argue that because of these misinterpretations, the derived black hole solutions and the Lagrangian densities presented in that paper are slightly inconsistent.
