Comment on: “Klein–Gordon oscillator under gravitational effects in a topologically charged Ellis–Bronnikov wormhole”

Abstract

In this paper, we analyze the results for the ground state of a Klein{Gordon oscillator under gravitational e®ects in a topologically charged Ellis{Bronnikov wormhole derived recently. We show that the authors failed to truncate a power-series and, consequently, could not obtain the desired solution to a di®erential equation. For this reason, their analytical expression for the ground-state eigenvalue is incorrect, a fact that a®ects all the conclusions drawn by the authors for the physical problem.
