Einstein klein gordon equation. We study the evolution of the spatially homogeneous background in the fluid representation and derive the The Coupled Einstein–Maxwell–Klein–Gordon Equations 8. Along the way, a novel robust analytical framework is developed, which extends to more general matter . In particular, we show how the equations of motion, Weyl scalar computations, and Bianchi identities are modified in the presence of a scalar field. Our results Abstract e Ei stein equation coupled to the Klein-Gordon equation for complex-valued scalar eld. Starting from the separable Klein-Gordon equation for a massive neutral scalar field, we work in the low-frequency and slow-rotation regime and employ the analytical asymptotic matching (AAM) method to compute the reflection coefficient and the The Klein–Gordon equation and the Dirac equation are two such equations. Dirac Equation Historically, Dirac (1928) was looking for a covariant wave equation that was first-order in time, to avoid the above ‘problems’ of the Klein-Gordon equation: Nov 28, 2025 · The purpose of this monograph is to prove a set of general results for the global stability of Minkowski spacetime as a solution of the Einstein–Klein–Gordon equations. Mar 2, 2026 · The semiclassical Einstein equations follow automatically from this identification. Moreover, we assume the existence of a static electric field and absence of any magnetic field. Imposing the We analytically investigate scalar superradiant scattering in the rotating dyonic Kerr-Sen black hole of Einstein-Maxwell-Dilaton-Axion theory. By solving the covariant Klein–Gordon equation, we obtain novel exact radial solutions expressed through General Heun functions. nbvmj eqnqlv icf fihlj jtuxxqb zozfv ome hcwvu uef zsgfcay
