Slowly rotating neutron stars with small differential rotation: equilibrium models and oscillations in the Cowling approximation
Cecilia Chirenti, Jozef Skakala, Shin'ichirou Yoshida
Newly born neutron stars can present differential rotation, even if later it should be suppressed by viscosity or a sufficiently strong magnetic field. And in this early stage of i…
No asymptotically highly damped quasi-normal modes without horizons?
Cecilia Chirenti, Alberto Saa, Jozef Skakala
We explore the question of what happens with the asymptotically highly damped quasi-normal modes ( fixed, ) when the underlying spacetime has no event horiz…
Aspects of General Relativity: Pseudo-Finsler extensions, Quasi-normal frequencies and Multiplication of tensorial distributions
Jozef Skakala
This thesis is based on three different projects, all of them are directly linked to the classical general theory of relativity, but they might have consequences for quantum gravit…
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…
Birkhoff-like theorem for rotating stars in (2+1) dimensions
Jozef Skakala, Matt Visser
Consider a rotating and possibly pulsating "star" in (2+1) dimensions. If the star is axially symmetric, then in the vacuum region surrounding the star, (a region that we assume at…
Birefringence in pseudo-Finsler spacetimes
Jozef Skakala, Matt Visser
Based on the analogue spacetime programme, and many other ideas currently mooted in "quantum gravity", there is considerable ongoing speculation that the usual pseudo-Riemannian (L…
