Convergence of an energy-preserving scheme for the Zakharov equations in one space dimensionMathematics of Computation, 58
In this paper, a new conservative finite difference scheme with a parameter θ is proposed for the initial-boundary problem of the Klein-Gordon-Zakharov (KGZ) equations. Convergence of the numerical solutions are proved with order O(h 2 + τ 2) in the energy norm. Numerical results show that the scheme is accurate and efficient.
