摘要
研究一类时滞微分方程的周期解与概周期解,运用比较定理和V函数法,得出该方程存在惟一的全局吸引的正周期解的充分条件,同时也研究了其概周期解的存在惟一性与一致渐近稳定性条件.
In this paper,a differential equation with delays is studied. By means of comparison throrem and V function method, we obtain sufficient conditions for the existence, uniqueness and global attractivity of positive periodic solution. In addition, the existence, uniqueness and uniform asymptotic stability of almost periodic solution are also studied.
