摘要 利用叠合度理论和Lyapunov泛函,研究一个具反馈和时滞变量的2种群周期竞争系统正周期解的存在性和全局稳定性,得到相应的充分条件。 The existence and global stability of positive periodic solutions of 2-species periodic Lotka-Volterra competition system with feedback comtrol and several deviating arguments are investigated by using the method of coincidence degree and Lyapunov functional.Some sufficient conditions are obtained.
