An application of the modified decomposition method for the solution of the coupled Klein–Gordon–Schrödinger equation

The modified decomposition method has been implemented for solving a coupled Klein–Gordon–Schrödinger equation. We consider a system of coupled Klein–Gordon–Schrödinger equation with appropriate initial values using the modified decomposition method. The method does not need linearization, weak nonlinearity assumptions or perturbation theory. The numerical solutions of coupled Klein–Gordon–Schrödinger equation have been represented graphically.
