通过构造Lyapunov函数研究了一类非自治的数学生物经济模型的概周期解的存在性,得到了保证概周期解存在的充分性判椐.
By constructing Lyapunov function, the existence of almost periodic solutions for a class of nonautonomous mathematical bioeconomy models is studied. The sufficient condition for guaranteeing the existence of almost periodic solutions is obtained.
