摘要
运用L iapunov函数方法,研究了一类四阶非线性微分方程解的有界性和稳定性,给出了解的有界性和稳定性的充分条件,所得结果包含并改进了已有文献的一些结论.
In this paper, the boundedness and stability of solutions for a class of fourth order nonlinear differential equations are studied by using the method of Hapunov function. The sufficient condition which guarantees the boundedness and stability of solutions are presented. The work improvs the existing results in references.
