Comment on the asymmetric variation of a finite mass harmonic like oscillator' '

Abstract

The paper asymmetric variation of finite mass harmonic like oscillator'' in the Results Phys 19 (2020) 103335, contains a sign mistake in the dynamical equation used . This, in turn, affects the equations and results that follow. Moreover, the authors plotted the momentu m operator (i.e., a differential operator (p) over cap= -i partial derivative/partial derivative x) against the coordinate x(t). This is here argued to constitute a conceptual quantu m mechanical error.
