  2. This paper consists of three parts : we first consider the non - autonomous predator - prey system with both beddirigton - deangelis functional response and dispersion. by using comparison theorem of differential equation, we study the permanance of the system. after that, by constructing suitable lyapunov function, we obtain some sufficient condition which guarantee the existence of globally asymptotically stable almost periodic solution of the system

  3. Each chapter of the paper reads as follows. firstly, the uniform persistence of the system is proved ; secondly, by using the independent subsystem method, the more brief sufficient conditions for the existence and global attractivity of the periodic solution and a mathematical example is obtained to show its practicality. finally, the conditions of the existence of the positive almost periodic solution which is uniformly asymptotically stable are derived by the razumikhin function method and a mathematical example is obtained

  4. In chapter 2, the almost periodic lotka - volterra model with m - predators and n - preys is considered. by constructing suitable lyapunov function, some sufficient conditions are obtained for the existence and global attractivity of a unique positive almost periodic solution of this model. our results generalize those ones of [ 18, 19, 23 26 ]

  6. Especially in recent score years, in autonomous and nonautonomous systems, the neutral, finite - delay, infinite - delay, diffusive, discrete, discrete - delay, generalized, difference and other style models were discussed on optimal harvesting, osillation, stability, global stability, and other asmptotic behaviors of logistic equation. reference were searched in [ l - 6 ], [ 10 - 18 ], [ 20 - 31 ], [ 34 ]. the periodic and almost periodic function logistic equation, which are widely studied recently, the results about the above are found on many kinds of magazines

    尤其是近二十多年來,在自治系統與非自治系統中有關有限時滯型,無限時滯型,中立型,離散型,擴散型,離散時滯型,廣義型,差分型logistic方程的最優捕獲策略,振動性,周期解,概周期解,漸近性態,全局性態等方向進行了各方面的研究,可參見文獻[ 1 - 6 ] , [ 10 - 18 ] , [ 20 - 31 ] , [ 34 ]
  7. We organized the whole paper as follow : in section 1, we introduce the background of this article in brief and give out the improved model and do some prepare works ; in section 2, we will prove the system is uniformly persistant under some conditions ; in section 3, we will prove the system is globally asymptotically stable by using lyapuvov function ; in section 4, we will give sufficient conditions of the existence, uniquness and global asymptotical stability of positive almost periodic, solutin of the almost, periodic system
