Comment on ‘Do electromagnetic waves always propagate along null geodesics?’

چکیده
We study the propagation of Maxwellian electromagnetic waves in curved spacetimes terms appropriate geometrical optics limit, notions signal speed, and minimal coupling prescription from theory flat spacetime. In course this, we counter a recent major claim by Asenjo Hojman (2017) to effect that limit is partly ill-defined G\"odel spacetime; thereby dissolve present tension concerning established results on wave optical limit.

Trapping of waves and null geodesics for rotating black holes
We present dynamical properties of linear waves and null geodesics valid for Kerr and Kerr–de Sitter black holes and their stationary perturbations. The two are intimately linked by the geometric optics approximation. For the nullgeodesic flow the key property is the r-normal hyperbolicity of the trapped set and for linear waves it is the distribution of quasi-normal modes: the exact quantizati...
متن کاملOn General Plane Fronted Waves. Geodesics
A general class of Lorentzian metrics, M0 ×R, 〈·, ·〉z = 〈·, ·〉x + 2 du dv + H (x, u) du2, with (M0, 〈·, ·〉x ) any Riemannian manifold, is introduced in order to generalize classical exact plane fronted waves. Here, we start a systematic study of their main geodesic properties: geodesic completeness, geodesic connectedness and multiplicity causal character of connecting geodesics. These results ...
متن کاملNull Geodesics in Five-Dimensional Manifolds
We analyze a class of 5D non-compact warped-product spaces characterized by metrics that depend on the extra coordinate via a conformal factor. Our model is closely related to the so-called canonical coordinate gauge of Mashhoon et al. We confirm that if the 5D manifold in our model is Ricciflat, then there is an induced cosmological constant in the 4D sub-manifold. We derive the general form o...
متن کاملNull Geodesics in Brane World Universe
We study null bulk geodesic motion in the brane world cosmology in the RS2 scenario and in the static universe in the bulk of the charged topological AdS black hole. We obtain equations describing the null bulk geodesic motion as observed in one lower dimensions. We find that the null geodesic motion in the bulk of the brane world cosmology in the RS2 scenario is observed to be under the additi...
متن کاملA Conformal Extension Theorem based on Null Conformal Geodesics
In this article we describe the formulation of null geodesics as null conformal geodesics and their description in the tractor formalism. A conformal extension theorem through an isotropic singularity is proven by requiring the boundedness of the tractor curvature and its derivatives to sufficient order along a congruence of null conformal geodesic. This article extends earlier work by Tod and ...
