研究了随机延迟微分方程复合θ-方法的稳定性。得到了复合θ-方法均方稳定(MS-稳定)和全局均方稳定(GMS-稳定)充分条件。数值算例及其方差的模拟结果验证了理论上推得结论的正确性。
The stability of composite θ-method for stochastic differential delay equation was studied. The sufficient conditions of MS-stability and GMS-stability of composite θ -method were obtained. The simulation results of the numerical examples and the variance of numerical examples verify the results obtained in theory.
