【摘要】 利用Ho lder不等式研究一类非线性项具时滞的二阶中立型时滞微分方程{r(t)[y(t)+p(t)y(t-τ)]′2m+1}′+q(t)f[y(t-σ)]=0(t>t0)的振动性.给出了该方程的解振动的若干充分条件,所得结果推广了已有的相应结论.更多还原

【Abstract】 It investigates the oscillation of one kind of non-linear second-order neutral differential equation with delay{r(t)[y(t)+p(t)y(t-τ)]′2m+1}′+q(t)f[y(t-σ)]=0(t>t0)in this paper using Holder inequality,and we give several sufficient conditions about oscillation for this kind of equation,the conclusions which we draw generalize the part conclusions.更多还原
