Convergence of an energy-preserving scheme for the Zakharov equations in one space dimension. (English) Zbl 0746.65066
An energy-preserving, linearly implicit finite difference scheme is presented for approximating solutions to the problem: $$iE_ t+E_{xx}=NE$$, $$N_{tt}-N_{xx}=(| E|^ 2)_{xx}$$, $$E(x,0)=E^ 0(x)$$, $$N(x,0)=N^ 0(x)$$, $$N_ t(x,0)=N^ 1(x)$$. First- order convergence estimates are obtained in a standard “energy” norm in terms of the initial errors and usual discretization errors.
