具阻尼项的二阶非线性中立型微分方程的振动准则
Oscillation criteria of second order nonlinear neutral differential equations with damping terms
摘要
Abstract
The purpose of this paper is to establish some new oscillation criteria for the second-order nonlinear neutral differential equations with damping terms which have the form[a(t)|z′(t)|α-1z′(t)]′+ b(t)|z′(t)|α-1z′(t)+ q(t)|x(σ(t))|β-1x(σ(t))=0,where z(t)=x(t)+p(t)x(τ(t)).Our theorems improve,extent and unify a number of related results reported in the literature.The wide application of the obtained criteria is illustrated via examples.关键词
