具有生育脉冲及垂直传染的SIS传染病模型的周期解
Periodic Solutions of an SIS Epidemic Model with Vertical Transmission and Birth Pulses
摘要
Abstract
This paper investigates a class of SIS epidemic model with vertical transmission and birth pulses.The existence and stability of the infection-free periodic solution and the endemic periodic solution are discussed by using discrete maps.Moreover,numerical results for phase portraits,periodic solutions,and bifurcation diagrams,which are illustrated with an example,are in good agreement with the theoretical analysis.关键词
