(2.12) The Einstein field equations in the weak field, slow motion limit take the form of Maxwell–like equations, and allow the description of general relativity in this regime

In this paper, we point out that the gravity dual of … Nettet16. mar. 2024 · 10. The linearized Einstein field equations in the Lorenz gauge (with g μ ν = η μ ν + h μ ν and h ¯ μ ν = h μ ν − η μ ν 2 h) are given by: h ¯ μ ν = − 16 π G c 4 T μ ν. This has the general solution: h ¯ μ ν = 4 π G c 4 ∫ T μ ν ( r → s, t − R / c) R d 3 r → s + ϕ μ ν. Where R = r → − r → s and ...

NettetIn general relativity, an exact solution is a solution of the Einstein field equations whose derivation does not invoke simplifying assumptions, though the starting point for that derivation may be an idealized case like a perfectly spherical shape of matter. Mathematically, finding an exact solution means finding a Lorentzian manifold equipped …
