## Abstract This paper is concerned with the standing wave in coupled non‐linear Klein–Gordon equations. By an intricate variational argument we establish the existence of standing wave with the ground state. Then we derive out the sharp criterion for blowing up and global existence by applying the

We prove the existence of the wave operator for the system of the massive Dirac-Klein-Gordon equations in three space dimensions
where the masses m, M>0. We prove that for the small final data w + ∈ (H 3 2 +l,1 ) 4 , (/ + 1 , / + 2 ) ∈ H 2+l,1 ×H 1+l,1 , with l = 5 4 -5 2q and 90 37 <q<6, there exists a unique global solution for system (1) with the final state conditions
→ 0 as t →∞.

## Abstract A predictor–corrector (P–C) scheme based on the use of rational approximants of second‐order to the matrix‐exponential term in a three‐time level reccurence relation is applied to the nonlinear Klein‐Gordon equation. This scheme is accelerated by using a modification (MPC) in which the
and b is real, g is a given nonlinear function, and f is a known function. In this paper, Adomian's decomposition scheme is presented as an alternate method for solving the nonlinear Klein-Gordon equa- The method is demonstrated by several examples. Comparing cal models in quantum mechanics [23][2
This paper deals with the regularity of the global attractor for the Klein}Gordon}Schro K dinger equation. Using a decomposition method, we prove that the global attractor for the one-dimensional model consists of smooth functions provided the forcing terms are regular.
