Título: Stability Analysis of a SIS Epidemic Model with Standard Incidence
Autores: Cruz Vargas-De-León


In this paper, we study the global properties of classic SIS epidemic model with constant recruitment, disease-induced death and standard incidence term. We apply the Poincaré-Bendixson theorem, Dulac.s criterion, and the method of Lyapunov function to establish conditions for global stability. For this system, three Dulac functions and two Lyapunov functions are constructed for the endemic steady state.
