摘要 为了进一步发展和完善时间模上动态方程的振荡理论,研究了时间模上一类二阶非线性中立型变时滞的动态方程[a(t)|y~Δ(t)|^(α-1)y~Δ(t)]~Δ+q(t)|x(δ(t))|^(β-1)x(δ(t))=0的振荡性(这里y(t)=x(t)+p(t)x(τ(t));α>0,β>0为实常数),得到该方程振荡的一些新准则,推广并改进了一些已有的结果. In order to develop and improve the theory about oscillation of dynamic equations on time scales,this paper is concerned with oscillations of certain second-order nonlinear neutral variable delay dynamic equation[a(t)|yΔ(t)|(α-1) yΔ(t)]Δ+q(t)|x(δ(t))|(β-1) x(δ(t))=0on a time scale T(where y(t)=x(t)+p(t)x(τ(t)),α0andβ0are real constants).We establish some new oscillation criteria for the equation.Some existing results in the literature are improved and extended.
