| Abstract: | The dynamic behaviors of a mathematical chemostat model with variable yield and nutrient recycling and periodically impulsive perturbation on substrate were considered.Using Floquet theory and small amplitude perturbation method,the condition in which the boundary periodic solution was globally asymptotically stable was established.Moreover,the permanence of the system was discussed in detail. |
