As for the massless case the solutions have a naked singularity at the origin. 4 The Dirac Equation The problems with the Klein-Gordon equation led Dirac to search for an alternative relativistic wave equation in 1928, in which the time and space derivatives are first order. Consequently, the two terms can be considered separately. It is believed that every relativistic quantum model describing a system without external interactions (a free system) is, in a sense, a special case of the Klein-Gordon equation; in particular, every solution of the potential formulation of free Maxwell's equations satisfies (3.

Attractors of the Einstein-Klein-Gordon System A key question in general relativity is whether solutions to the Einstein equations, viewed as an initial value problem, are stable to small perturbations of the initial data. we solve the relativistic Hamilton-Jacobi equation in an open cosmological universe with a horn topology. - From Einstein to Klein-Gordon - Quantum Mechanics and Relativity Aline Ribeiro Department of Mathematics University of Toronto March 24, 2002 Abstract We study the development from Einstein's relativistic energy-momentum relation for free particles, E2 − c2p~2 − m2 0 c 4 = 0, to the Klein-Gordon equation, [−~2∂2 t+c2~2∆−m2 0 c. We examine the Einstein equation coupled to the Klein-Gordon equation for a complex-valued scalar field. I am a little confused about a few papers I read on the Einstein-Klein-Gordon (EKG) equations. On the basis of qualitative theory of differential equations it is shown that dynamic system based on the system of Einstein - Klein - Gordon equations with regard to Fr. We examine the Einstein equation coupled to the Klein-Gordon equation for a complex-valued scalar eld. I go over four-vector notation, Four-gradient, and writing the equation in terms of the D'Alambertian. The Klein-Gordon Equation and the Schrodinger’s Equation deserve mathematical impact from me. The Klein–Gordon equation (Klein–Fock–Gordon equation or sometimes Klein–Gordon–Fock equation) is a relativistic version of the Schrödinger equation. The Klein-Gordon equation (Klein-Fock-Gordon equation or sometimes Klein-Gordon-Fock equation) is a relativistic version of the Schrödinger equation. and field together solve the Einstein-Klein-Gordon equations. Lindblad and A. In the new formulation of the method, we succeed to cover wave-Klein-Gordon systems containing "strong interaction" terms at the level of the metric, and then generalize our method in order to establish a new existence theory for the Einstein equations of general relativity. Klein -Gordon equation. It is second-order in space and time and manifestly Lorentz-covariant. In addition, the essential difference between the exact solution and the post-Newtonian approximate solution is also shown. Particular solutions of the Klein. Key points for the proof of sharpness: quasimodes on Kerr-AdS 6. What is really cool about this equation is that you can find plane wave solutions to it relatively easily. [2, 59, 50]. For example, Schrödinger equation and Klein-Gordon equation are typical dispersive equations, which appear in quantum physics or relativistic quantum field theory. Stability and instability in spherical symmetry of Reissner-Nordström black holes for the Einstein-Maxwell-Klein-Gordon model. In Chapter 15 of the 4 th edition of Intermediate Physics for Medicine and Biology, Russ Hobbie and I present the Klein-Nishina formula (Eq. The Einstein-Klein-Gordon (EKG) equations. General Mathematics [math. Solving the Maxwell-Klein-Gordon equation in the Lattice Gauge Theory formalism Snorre H. These two equations together are known as the Einstein-Klein-Gordon system. Klein-Gordon equations can be viewed as a consequence of introduc-ing a memory function given by −iδ and δ(1), respectively. The Oskar Klein Memorial Lecture series has become a very successful tradition in Swedish physics since it started in 1988. A note on the Klein–Gordon equation in the background of a rotating black hole Horst R. In this paper, we extend the hyperboloidal method from Minkowski space to Lorentzian spacetimes.

The result is the Klein-Gordon equation, which describes the waves as-. Abstract, references and article information Full-text PDF Global regularity of solutions of the Einstein-Klein-Gordon system: A review Alexandru D. In field theory, the Proca action describes a massive. , a free parameter. where H is the Hamiltonian and [·,·] is the commutator of A and H. its energy, in the Planck–Einstein equation, E = hf. Einstein-Cartan-Klein-Gordon(ECKG)cosmology. We examine the Einstein equation coupled to the Klein-Gordon equation for a complex-valued scalar field. References [1]W. We apply a geometric method which relates the Lie symmetries of the Klein–Gordon equation with the conformal algebra of the underlying geometry.
