【Abstract】 In this paper,a finite difference scheme is proposed for generalized symmetric Regularized-Long-wave(SRLW)equation.Existence and uniquence of numerical solutions are shown.A priori estimate and second order convergence as well as conservation of energy of the finite difference approxmate solution are discussed.
