摘要
本文建立了一个具有常恢复率的同质人群艾滋病梯度传染模型,其中的性接触数是人群变量的函数,讨论了平衡点的存在性和稳定性,推广和改进了一些相关的己有结果.
A model for HIV transmission is formulated for homogeneous population with stages of progress to AIDS, with constant recruitment, and with the population size de-pendent contact function. The existence and stability of the equilibria for the model are discussed, some existed results are extended and improved in this paper.
