| Abstract: | In this paper a class of SIRS epidemiological modelswith nonlinear incidence rrates are studied. The models are given byLin Weimin, authors proved the existence and uniqueness of limitcyclen in some parameter regions. When incidence coefficient is afunction of the time,the parameter rogions in which the models appearchoas behavior are given. |
