摘要
讨论二阶线性微分方程(r(t)x′)′+p(t)x′+q(t)x=0的振动性,利用Ricati方程的形式特点,结合积分平均技巧,得到了新的判别准则,推广并改进了以往的若干结果.
By using the form of Ricattis equation and combining it with the technique of integral averages, oscillation criteria for second order differential equations (r(t)x′)′+p(t)x′+q(t)x= 0 are obtained. The results are generalizations and improvements of earlier results.
