摘要
本文讨论具有有限多个奇点的广义Liénard系统解的有界性,得到一组保证系统的解正向有界的充分条件,进而得到存在极限环的条件。
This paper deals with the boundedness of the solutions for the generalized Lienard system with a finite number of singular points, and gives some sufficient conditions for all solutions of the system to be bounded for t≥0. Moreover, the conditions for the existence of limit cycles for the system are obtained.
