摘要
研究了一类二阶半线性中立型阻尼微分方程的振动性,利用Yang不等式,广义Riccati变换和H函数,获得此类方程所有解振动的新的充分条件.
In this paper, Oscillation for a class of second-order half-linear neutral damped differential equation with time-delay is studied. By means of Yang-inequality, the generalized Riccati transformation and fuction H, some new sufficient conditions of oscillation are given for all solution of the equation.
