中文摘要: |
研究了一个指数型非线性随机差分方程组,并考虑了双随机因素的扰动,利用平衡点的平移变换、Jaccobi线性化、Lyapunov函数法及稳定性理论等得到该模型平衡解渐近均方稳定和依概率稳定的充分条件,并用数值仿真说明了所得结论的正确性。 |
英文摘要: |
In this paper, asymptotic behavior of a class of exponential type system of difference equations is investigated, taking the random perturbations of doubly stochastic factors into account. Using Jaccobi linearization, Lyapunov function method and stability theory, the sufficient conditions are obtained for stability in probability of both equilibriums of the model. Finally, the theoretical results are supported with numerical simulations. |
