摘要
研究了一般形式的二阶线性微分方程x″(t)+p(t)x′(t)+q(t)x(t)=0的振动性质,得到了这类微分方程振动的准则,从而推广了文献[1]的结果.
Some oscillation properties are studied for general linear second order ordinary differential equations of the formx″(t)+p(t)x′(t)+q(t)x(t)=0.We obtained some new oscillation criteria and extend some earlier results of Deng in reference [1].
