考虑了媒体报导影响下的SEI模型,并且假设传染率为(μ1-μ2f(I))SI.通过构造Liapunov函数得到了平衡点全局渐近稳定的充分条件.
- Abstract:
-
We consider global properties for a SEI model with impact of media, assuming that the rate of transmission is controlled by an unspecified function ( μ1 - μ2 f( I) ) SI. We develop Liapunov functions which enable us to obtain sufficient conditions of a globally asymptotically stable equilibrium state.
