摘要
利用Riccati变换及积分平均技巧,建立一类具有非线性中立项及分布偏差变元的二阶中立型方程的振动准则,我们的结果推广并改进了一些已有的结果.
By the use of the integral averaging technique and Riccati transformation, we establish some oscillation criteria for a class of second order neutral differential equations with non-linear neu- tral term and distributed deviating argument. The results obtained are extensions of some known re- sults in the literature.
