一类非线性系统解的有界性

ON THE BOUNDEDNESS OF THE SOLUTIONS OF A CLASS OF NONLINEAR DIFFERENTIAL SYSTEM

研究了一类非线性微分系统解的有界性 ,所获结果可应用于Li啨ｎａｒｄ类型的方程 。

This paper studies the boundedness of solutions of a second-order nonlinear differential system. A new sufficient condition for all solutions of this system to be bounded is obtained ,which extends and improves some results associated with the same problem in literature.
