摘要
给出非线性二阶阻尼微分方程新的振动准则,它们仅依赖于区间[t0,∞)的某些子区间序列的信息,不需要依赖于整个半直线,所得结果推广和改进了某些最近的结果.
In this paper, some new oscillation criteria are presented for linear differential equations that are different from most known ones in information only on a sequence of sub-intervals of [t0, ∞), rather than extend and improve some recent results. certain classes of second-order nonthe sense that they are based on the on the whole half-line. The results
