9. Introduction into perturbation theory in general relativity 2 (Inflationary perturbations 3)
Today I will continue our discussion of the perturbation theory in general relativity (please see the previous post here); in particular, I will focus my attention on the issue of gauge invariance.
1. (…)
8. Introduction into perturbation theory in general relativity (Inflationary perturbations 3)
Before turning to the discussion of the perturbation theory in general relativity, let me briefly remind the outline of the two previous posts (1 and 2). (…)
