General framework of higher order gauge invariant perturbation theory
Based on the gauge invariant variables proposed in [K. Nakamura, Prog. Theor. Phys. 110 (2003), 723.], general framework of the second order gauge invariant perturbation theory on arbitrary background spacetime is considered. We derived formulae of the perturbative Einstein tensor of each order, which have the similar form to the definitions of gauge invariant variables for arbitrary perturbati...
متن کامل“ Gauge ” in General Relativity : — Second - order general relativistic gauge - invariant perturbation theory —
As in the case of the other gauge field theories, there is so called “gauge” also in general relativity. This “gauge” is unphysical degree of freedom. There are two kinds of “gauges” in general relativity. These are called the firstand the second-kind of gauges, respectively. The gauge of the first kind is just coordinate system on a single manifold. On the other hand, the gauge of the second k...
متن کاملSecond-Order Gauge Invariant Cosmological Perturbation Theory Einstein Equations in Terms of Gauge Invariant Variables
Following the general framework of the gauge invariant perturbation theory developed in the papers [K. Nakamura, Prog. Theor. Phys. 110 (2003), 723; ibid. 113 (2005), 481], we formulate second-order gauge invariant cosmological perturbation theory in a four-dimensional homogeneous isotropic universe. We consider perturbations both in the universe dominated by a single perfect fluid and in that ...
متن کاملShort note on second-order gauge-invariant cosmological perturbation theory
The second order perturbations in Friedmann-Robertson-Walker universe filled with a perfect fluid are completely formulated in the gauge invariant manner without any gauge fixing. All components of the Einstein equations are derived neglecting the first order vector and tensor modes. These equations imply that the tensor and the vector mode of the second order metric perturbations may be genera...
متن کاملGeneral Relativistic Magnetoionic Theory
Abstract. We have developed methods for tracing rays and performing radiative transfer through a magnetoactive plasma in a general relativistic environment. The two electromagnetic plasma modes propagate differently due to a combination of dispersive and gravitational effects. We have found that, when given an appropriate environment surrounding the central black hole, it is indeed possible to ...
