Perturbative Approach to the Quasinormal Modes of Dirty Black Holes
P. T. Leung, Y. T. Liu, W. -M. Suen +2
Using a recently developed perturbation theory for uasinormal modes (QNM's), we evaluate the shifts in the real and imaginary parts of the QNM frequencies due to a quasi-static per…

Logarithmic perturbation theory for quasinormal modes
P. T. Leung, Y. T. Liu, W. M. Suen +2
Logarithmic perturbation theory (LPT) is developed and applied to quasinormal modes (QNMs) in open systems. QNMs often do not form a complete set, so LPT is especially convenient b…
