二阶非线性微分方程解的有界性

BOUNDEDNESS OF SOLUTIONS OF A CLASS OF SECOND ORDER NONLINEAR DIFFERENTIAL EQUATIONS

借助于辅助函数和基本不等式得到了二阶非线性微分方程一切解均有界的判定方法．

With the aid of auxiliary funtions and integral inequalities some sufficient conditions are obtained under which all solutions of a class nonlinear differential equations belong to L￣∞[a,∞)。
