| contents | This is the Part III paper of our series of papers on a gauge-invariant perturbation theory on the Schwarzschild background spacetime. After reviewing our general framework of the gauge-invariant perturbation theory and the proposal on the gauge-invariant treatments for $l=0,1$ mode perturbations on the Schwarzschild background spacetime in [K.~Nakamura, arXiv:2110.13508 [gr-qc]], we examine the problem whether the $l=0,1$ even-mode solutions derived in the Part II paper [K.~Nakamura, arXiv:2110.13512 [gr-qc]] are physically reasonable, or not. We consider the linearized versions of the Lemaître-Tolman-Bondi solution and the non-rotating C-metric. As the result, we show that our derived even-mode solutions to the linearized Einstein equations actually realize above two linearized solutions. This fact supports that our derived solutions are physically reasonable, which implies that our proposal on the gauge-invariant treatments for $l=0,1$ mode perturbations are also physically reasonable. We also briefly summarize our conclusions of our series of papers. |
