奇数阶中立型时滞微分方程的线性化振动性

LINEARIZED OSCILLATIONS FOR ODD-ORDER NEUTRAL DELAY DIFFERENTIAL EQUATIONS

考虑奇数阶中立型非线性微分方程本文在允许P（t）-1振动的条件下给出了该方程的几个线性化振动结果．

Consider the odd-order nonlinear neutral equation (x(t)-p(t)g(x(t-T)))＋Q(t)h(x(t-σ)) = 0.We establish some linearized oscillation results of this equation when p(t) -1 is allowed to oscillate.
