Comparing a Gauge-Invariant Formulation and a 'Conventional Complete Gauge-Fixing Approach' for l=0,1-Mode Perturbations on the Schwarzschild Background Spacetime
Autor: Kouji Nakamura
Publikováno v: Universe, Vol 10, Iss 11, p 420 (2024)
This article provides a comparison of the gauge-invariant formulation for l=0,1-mode perturbations on the Schwarzschild background spacetime, proposed by the same author in 2021, and a “conventional complete gauge-fixing approach” where the spher

Formal Solutions of Any-Order Mass, Angular-Momentum, and Dipole Perturbations on the Schwarzschild Background Spacetime
Autor: Kouji Nakamura
Publikováno v: Letters in High Energy Physics, Vol 2021, Iss 1 (2021)
Formal solutions of any-order mass, angular-momentum, dipole perturbations on the Schwarzschild background spacetime are derived in a gauge-invariant manner. Once we accept the proposal in [K. Nakamura, Class. Quantum Grav. \({\bf 38}\) (2021), 14501
