摘要
研究RFDE的周期解存在性问题,推广了[1]中周期解存在性的经典结果。给出RFDE解的弱最终有界性和局部等度有界性的定义和充分性判据。
In this paper the existence of periodic solutions of RFDE is discussed. We gene- ralize the classical result of tbe existence of peeriodic solutions in [1] and give the definitions of weak ultimate boundedness and local equiboundedness for RFDE and the sufficient criterion of weak ultimate boundedness and local equi-boundedness.
