复杂网络上随机禽流感模型解的存在唯一性
摘要:
考虑到随机噪声及个体间的异质性对禽流感传播的影响,建立了复杂网络上具有标准Wiener过程影响的随机禽流感模型。应用算子半群理论研究了该模型解的适定性,证明了解的存在性、唯一性及它对初始条件的连续依赖性。
Considering the impact of stochastic noise and heterogeneity between individuals on the spread of avian influenza, a stochastic avian influenza model with standard Wiener process on a complex network is established in this paper. The well-posedness of the solution of the model is studied by using the semigroup theory of operators, the existence and uniqueness of the solution and its continuous dependence on initial conditions are proved.
