摘要
研究了具有正负系数的一阶中立型时滞微分方程[x(t)-px(t-τ)]+qx(t-σ)-rx(t-ρ)=0,其中p∈(0,1),利用适当的特征方程和不等式,建立了解的新振动准则。
The oscillation of the differential equation of the first neutral delay [x(t)- px(t- τ)]’ +qx(t-σ)- rx(t-ρ) =0 is studied in this paper, where p∈ (0,1), the sufficient conditions for oscillation of the equation are obtained by suitable inequality and characteristic equation.
