... occurring geometric property of relativistic theories of gravitation, the gauge theory of the Poincaré group leads to its presence and the occurrence of cosmological singular- ities can be less generic ... conjugation in Riemannian geometries is also discussed in detail. The Maxwell field strength is written in this language, and many useful identities are given. The curvature spinors of gen...

... 1 . (1.63) Then ingoing null geodesics are described by v = constant, outgoing ones by u = constant, see figure 1.8. We define ingoing Eddington–Finkelstein coordinates by replacing the ‘Schwarzschild ... equation: R µν − 1 2 Rg µν Einstein tensor G µν + g µν = κ T µν . (1.44) The value κ := 8 G/ c 4 of Einstein’s gravitational constant can be determined by a transition to the N...

This follows by getting back what we start with ... equation (1.29). Assuming these are negligible and substituting Λ = constant, results in R ∝ exp(t). The acceleration is positive, corresponding to an accelerating expanding un...
