摘要 将线性θ-方法用于求解R(α,β_1,β_2,γ)类非线性中立型延迟积分微分方程,结果表明A-稳定的线性θ-方法(也即1/2≤θ≤1)是渐近稳定的,最后的数值试验验证了所获理论结果的正确性. Linearθ-methods are adapted for solving a class R(α,β1,β2,γ) of nonlinear neutraldelay integro-differential equations.It is proved that an A-stable linearθ-method(i.e.1/2≤θ≤1) is asymptotic stability.Numerical test is given to confirm the theoreticalresults.
