Einstein–Klein–Gordon spacetimes in the harmonic near-Minkowski regime
Einstein–Klein–Gordon spacetimes in the harmonic near-Minkowski regime
We study the initial value problem for the Einstein–Klein–Gordon system and establish the global nonlinear stability of massive matter in the near-Minkowski regime when the initial geometry is a perturbation of an asymptotically flat, spacelike hypersurface in Minkowski spacetime and the metric enjoys the harmonic decay 1/r (in terms of …
