Abstract

The goal of this short note is to provide a simpler derivation of the effective potential surrounding a Schwarzschild black hole for spherically symmetric perturbations in the framework of torsion bigravity than the one presented in [V. Nikiforova, Spherically symmetric perturbations of a Schwarzschild black hole in torsion bigravity, Phys. Rev. D 104, 024032 (2021).]. We also discuss the unicity of the reduction process that leads to the potential.
