摘要:

应用变分迭代方法求解一类中立型消失时滞微分方程. 通过选取适当的拉格朗日乘子, 得到了求解这类问题的迭代公式, 进而计算近似解. 通过比较变分迭代方法和Runge-Kutta法求解具体问题的绝对误差, 表明变分迭代方法是求解消失时滞微分方程的一种有效方法.

Abstract:

The variational iteration method was applied to solving neutral functional differential equations with vanishing delays. After determining an appropriate Lagrange multiplier, the approximate solutions can be readily obtained. Futhermore, some illustrative examples were given to show the efficiency of the method. We also compared these results with those given by RungeKutta method.

Key words: variational iteration method, RungeKutta method, neutral, functional differential equations
