摘要
通过构造 Lyapunov 函数,研究一类具有非线性捕获项的捕食系统概周期解的存在性,得到了保证概周期解存在的充分条件,并举例说明可行性.
In this paper, the positive almost periodic solution for a predator-prey model with nonlinear harvesting is considered.Sufficient conditions are established for the existence of almost periodic solution of the system by constructing a suitable Lyapunov function. An example together with its numerical simulation is carried out to show the feasibility of the main results.
