摘 要: | 建立了中立型Emden-Fowler泛函微分方程(r(t)z′(t)|~(α-1)z′(t))′+q(t)|x(δ(t))|~(β-1)x(δ(t))=0,t≥t_0的若干新的振动准则,其中z(t)=x(t)+p(t)x(τ(t)),α0,β0为常数.所得的结果推广和改进了近期文献的某些熟知的结果.

Abstract: | In this paper we establish some new oscillation criteria for the generalized EmdenFowler functional differential equations of neutral type of the form Where z(t) =x(t) + p(t)x(τ(t)),α > 0andβ > 0.Our results improve some known results which were published recently in the literatures. |
