The causal structure of spacetime is a parameterized Randers geometry
Jozef Skakala, Matt Visser
There is a by now well-established isomorphism between stationary 4-dimensional spacetimes and 3-dimensional purely spatial Randers geometries - these Randers geometries being a pa…
Quasi-normal frequencies: Semi-analytic results for highly damped modes
Jozef Skakala, Matt Visser
Black hole highly-damped quasi-normal frequencies (QNFs) are very often of the form (offset)} + i n (gap). We have investigated the genericity of this phenomenon for the Schwarzsch…
Generic master equations for quasi-normal frequencies
Jozef Skakala, Matt Visser
Generic master equations governing the highly-damped quasi-normal frequencies [QNFs] of one-horizon, two-horizon, and even three-horizon spacetimes can be obtained through either s…
Highly-damped quasi-normal frequencies for piecewise Eckart potentials
Jozef Skakala, Matt Visser
Highly-damped quasi-normal frequencies are very often of the form omega_n = (offset) + i n (gap). We investigate the genericity of this phenomenon by considering a model potential…
Bi-metric pseudo-Finslerian spacetimes
Jozef Skakala, Matt Visser
Finsler spacetimes have become increasingly popular within the theoretical physics community over the last two decades. Because physicists need to use pseudo-Finsler structures to…
Semi-analytic results for quasi-normal frequencies
Jozef Skakala, Matt Visser
The last decade has seen considerable interest in the quasi-normal frequencies [QNFs] of black holes (and even wormholes), both asymptotically flat and with cosmological horizons.…
