具有Beddington-DeAngelis反应的食物链模型的渐近周期解
Asymptotical Periodic Solution of a Food-Chain Model with Beddington-DeAngelis Functional Response
摘要
Abstract
A food-chain model with Beddington-DeAngelis functional response was investigated .Assuming that the coefficients of system were all asymptotical periodic functions and by means of constructing a suitable Liapunov function, the conditions of the systemic unique asymptotical periodic solution which was globally as -ymptotically stable were obtained .It is shown that the coefficients of system are under some suitable condi-tions, the unique asymptotical periodic solution w hich is globally asymptotical stable is exist in the system . Result which is obtained from the investigation is a good complement to the earlier publications .关键词
