Gauge Invariant Variables in Two-Parameter Nonlinear Perturbations
The procedure to find gauge invariant variables for two-parameter nonlinear perturbations in general relativity is considered. Up to third order perturbations, it is shown that appropriate combinations of nonlinear metric perturbations and lower order one are transformed as the gauge transformation of linear order metric perturbations. This implies that gauge invariant variables for the higher ...

متن کاملGauge-Invariant Perturbations of Varying-Alpha Cosmologies
Using a gauge-invariant formalism we derive and solve the perturbed cosmological equations for the BSBM theory of varying fine structure ’constant’. We calculate the time evolution of inhomogeneous perturbations of the fine structure constant, δα α on small and large scales with respect to the Hubble radius. In a radiationdominated universe small inhomogeneities in α will decrease on large scal...
متن کاملSecond Order Gauge-Invariant Perturbations during Inflation
The evolution of gauge invariant second-order scalar perturbations in a general single field inflationary scenario are presented. Different second order gauge invariant expressions for the curvature are considered. We evaluate perturbatively one of these second order curvature fluctuations and a second order gauge invariant scalar field fluctuation during the slow-roll stage of a massive chaoti...
متن کاملGauge invariant metric perturbations during reheating
The possible amplification of gauge invariant metric fluctuations in the infrared sector are very important during reheating stage of inflation. In this stage the inflaton field oscillates around the minimum of the scalar potential. The evolution for the super Hubble scales gauge invariant metric fluctuations can be studied by means of the Bardeen parameter. For a massive scalar field with pote...
