| Abstract: | A finite difference method with accuracies of fourth order in space and second order in time is proposed for time-periodic solutions of a nonlinear parabolic equation with time delay.A monotone iterative scheme is developed for proving the existence and uniqueness of the periodic solutions of the nonlinear discrete scheme,and the computational algorithms for the periodic solutions are also provided.The convergence of the discrete scheme is discussed. |
