一类具有媒体报道的传染病模型
A Class of Epidemic Model with Media Coverage
摘要
Abstract
In this paper, the media coverage M is considered as a function of time t. Using discontinuous function β/ (1 + εMI) to describe the influence of media coverage on the infection rate, a piecewise-smooth SIM epidemic model is established. The existence of the nonnegative equilibrium of the model is given. The local stability of the equilibrium of the system is obtained by using the linear stability theory of differential equations. A sufficient condition for global asymptotic stability of positive equilibrium is given by using the Poincare-Bendixon theorem.关键词
