利用第二加性复合矩阵证明了唯一地方病平衡点的全局渐近稳定性.
Abstract
In this paper
an epidemic model with constant input and nonlinear incidence rate is investigated
and the basic reproductive number R0 which determines the outcome of the infectious disease is found.The disease-free equilibrium is globally asymptotical when R01.Using second additive compound matrix proves that the unique endemic equilibrium is globally asymptotical stable when R01.
