Analysis of a class of oral chemostat model with time delay and pulse input
摘要
Abstract
An oral chemostat model with periodic pulse and time delay is discussed in this pa-per.Using the comparison theorem of impulsive differential equations,persistence theory and floquet operator theory,the existence of the microorganism-free periodic solution is proved, which is globally attractive under some critical conditions.Moreover,the sufficient conditions on permanence of the system is obtained.Finally,under the condition ofθ1<1|θ2>1 ,some numerical simulations are given to illustrate the main results.关键词
