研究一类具有交错扩散的害虫流行病控制模型。讨论反应扩散系统惟一的正常数平衡解的全局稳定性,建立正平衡解上下界的先验估计,证明了交错扩散系统非常数正平衡解的存在性。
An epidemic model for pest control is studied in this paper.The global stability of a unique positive constant steady state for the reaction-diffusion system is analyzed,and then a prior upper and lower bounds for all possible positive steady state are established.Finally,the formation of a stationary pattern for a cross-diffusion system is proved.
