近年来,关于一阶线性中立型泛函微分方程的振动性已有不少结果,但对于一阶非线性中立型泛函微分方程的振动性结果迄今很少见到。对下列的中立型泛函微分方程其中:P,τ,σ为正常数,Q(t),h(t)∈C[t_0,+∞),Q(t)>0,f(x)∈C(R,R),当x≠0时,Xf(x)>0。本文建立了振动性的两个结果。 相似文献

OSCILLATORY AND ASYMPTOTIC BEHAVIOR OF A CLASS OF FIRST ORDER NEUTRAL DIFFERENTIAL EQUATION WITH PIECEWISE CONSTANT DELAY 总被引:1,自引:0,他引:1
冯月才 《Annals of Differential Equations》2004,20(1):37-40
The oscillatory and asymptotic behavior of a class of first order nonlinear neutral differential equation with piecewise constant delay and with diverse deviating arguments are considered. We prove that all solutions of the equation are nonoscillatory and give sufficient criteria for asymptotic behavior of nonoscillatory solutions of equation. 相似文献
